Compression test first. Once the head is off lap in the valves. Always re adjust the valve clearances. Never ever use metal to metal like you did removing the head, use a block of hardwood and get some wd40 down the threads.

One or a couple of fuel injectors is causing the white smoke while under pressure. Remove them and have them cleaned properly. You may want to try to clean them yourself. Great video as usual.

I was thinking the exact same thing that an injector was fouled and had a bad spray pattern. On top of that, are you sure the thermostat isn’t in upside down? I’m not sure but I would think the big side with the spring should be on the hot side which is the engine side not the tank side. Someone please correct me if I’m incorrect in my thinking.

You should still adjust the valve lash, even with the same pushrods

i will add that valve adjustment is normal Maintenace as they get tighter as you run them. the valves beat into the head which tightens lash.

[@woodboat3G]

@@Rushinglc most diesels do not have hydraulic lifters

[@gaz-3711]

Other may have said it. Should have reconditioned the valves. Lap and swap the valve oil seals. The gasket kit had them sat there. Then regardless of of if may be ok should always check the valve clearance and lash. Changes the case filters and breathers. Check the inlet manifold for sludge and clean incase it is ingesting oil from a breather. You can do it all by hand so the only tools needed is a valve spring compressor, a lapping tool and valve bedding paste. Plenty of tutorials on youtube to point out how it is done would recon the injectors too by pulling them and sending them for a clean. (not a job for armatures) don't use metal to metal one scratch is enough to mess the block or head face

[@neillambton4065]

You will probably find the white smoke was due to an excess of engine oil. I`ve heard of this problem several times before, deisel oil mixed with engine oil burns with white smoke, it`s caused by excessive pressure in the crankcase causing blow by, meaning the oil being forced up beside the pistons. The white smoke would have stopped eventually when enough had blown by, however, that in itself can cause problems if not tackled quick enough.

[@lauri4403]

i think if theres much blow my by the piston rings or something. the pistons should me covered by oil. there was none. you should take intake mainfold off and look if theres oil. and you should check the valve clearances soon coz u chance the head gasket. but nice to see there no more white smoke. take care.

[@brianr561]

remove the cylinder head, turn it upside down. pour gasoline in top of each cylinder. See if any valve leaks. or pour gasoline into exhaust and intake ports to check for valve leaks. reseat the valves if any leaks. I would also check valve guides and valve seals. I suspect it is a worn valve guide and / or valve seal causing engine oil entering into combustion chamber.

[@guggesalven]

If there is excess oil, and it begins to burn in the cylinders it will begin to run-away on "full throttle" and may even over rev. so it's probably not due to excess oil.

[@robertoeduardoquintela4192]

Usually white smoke means you are burning diesel and oil. It may be because exces of oil presure and in the worth case failure in the rings qho let pass oil into de cilinders. Hope that in this case have been the first. Thanks for your videos.

[@777rogerf]

The high quality episode and your musical sense of humor (the majestic opening) are enjoyable as usual.

[@billyslide7645]

I believe it was the overfill of oil. The smoke was burning oil. At first I thought it was the Valve stems and/or valve stem seals. When the Valve stem guides wear and the seals get old, oil will come into the combustion chamber, causing the ugly burning old smoke. However, having too much oil in the crank case will cause the to ‘blow by’ the piston rings, especially at high RPMs.

[@johnnyzander1466]

Considering the white smoke (unburned diesel or the pump set too early) and how the engine shook at higher revs, my money is on bad / clogged injectors. I think the thing that helped the most in your case was the injectorcleaner in the diesel. I would recommend injector renovation and checking the pump setting.

[@walkersamdahl3424]

Yeah I noticed what seemed like excessive vibration as well.

[@peterk2455]

Before stripping down an engine determine if that is needed. Start with a compression, or better yet a leak down test. While at it pressure test the cooling system, look at your water cooled exhaust system, check for corrosion and leaks. Sea water can get hot enough to make steam. One system I saw had raw sea water seeping through a small crack in the exhaust manifold, it turned to steam and created 'smoke'. Check your fuel ( take a sample and really LOOK at it), fuel quality varies from marina to marina. It's not always diesel that is being pumped into your tank. I've seen old cooking oil added at some places. Check the tanks, delivery lines, water separator and filters. Marine fuel tanks can get very dirty. Check you fuel injectors, for pressure, delivery rate and spray pattern. Many diesels have clogged injectors and a simple clean makes a big difference. Your engine may need cleaned/rebuilt injectors instead of removing the head. If you remove the head you may as well overhaul it. Remove and re-seat the valves, replace valve seals etc. You've already bought all the bits with the head gasket. Good vids.

[@alext8828]

That white smoke looked like it was hanging in the air. Would steam do that?

[@1Jurbo]

don't forget to retorque after 50 operation hrs and adjust your valve rocker arms

[@matui6983]

Undoing the 4 bolts at the top of the injectors will do absolutely nithing in bleeding the air to help it start faster. They are the backleak/return bolts so you could bleed air from there forever and it will never get to the high pressure side of the inhector nozzle. Bleed the filter, possibly open bleed screw on the mechanical governor injector pump then crack open each injector pipe, crank the engine until air is purged, tighten the nuts and engine will fire up way quicker than it has been. Saves battery and starter. 4236 Perkins are a very very good engine.

[@johncollier608]

Oh well, at least the egine got a good service, for which your fellow river users will, no doubt thank you. Thanks for sharing. From the UK.

[@boatingboy5337]

I run a diesel additive all the time . Keeps the injectors clean. Don't for to re tighten the head after the engine has been run for a few hours your manual should give you information about this. I would also check the valve clearances when you have the rocker cover off. If the settings/gaps are too large the valves don't open fully and can be damaged and the engine doesn'trun as well as it could. The other thing is that the dimension between the cam followers and the rocker arms may have changed with the new gasket as the old one may have been compressed over the years. The issue of smoke can be caused by the over fill of oil. I enjoy you videos thank you for taking the time to make them. J

Gday Crew,, When you removed the cyl head you should have replaced valve stem seals & adjusted the valve clearences ... Injectors ,can cause smoke if they are dirty or leak ,or need resetting ,also fuel sould be turned off after use (to stop syphon or back flo ). A poorly timed fuel pump can cause smoke too, However , if you had a high.oil level in engine sump ,, iit looks like you may have loose leaking , or dirty injectors dripping fuel causing lube oil dilution , over filling the sump . Also check fuel tank for water contamination, from deck filling point. Cheap injector pump cleaning kits are on ebay . Respect

good job getting the head off and replacing the gasket. when i did a similar job, it was recommended that we check to see. how flat the head was and machine it if necessary. i agree with the others about the valve lash.

[@Cheers_Warren]

Looks like a Perkins 4.236. Great engines. Glad you fixed the white smoke issue. A lot of back yard mechanics with different opinions in comments! White smoke is caused by bad headgasket or unburnt fuel oil(usually). But the other obvious cause of white smoke is lube oil getting into the exhaust. Since lowering the oil level fixed the problem then your crank case breather system need cleaning/checking as it was allowing lube oil to get into the exhaust. There is a breather/crankcase vent and a blow by hose . Check both . Cheers warren

[@gaz-3711]

Yep it is a perkins. Ripped enough apart to ping it. Also is marked on the gasket kit :D

[@markbooysen9412]

For future remember, 1. White blueish smoke means burning oil. So there is oil getting into the combustion chamber. Usually due to oil rings being shot or valve stem seals or over filling the engine with oil. The white smoke will also smell like burning oil. 2. A faulty head gasket most often results in large clouds of sweet smelling white steamy smoke coming from the exhaust. This is caused by antifreeze leaking past the gasket and into the cylinders, where it is turned to steam as part of the combustion process. Less common, but still possible, is a leak from an oil passage to the cylinder, which would cause blueish smoke. Either of these types of gasket failure will also allow combustion pressure into the cooling system, or oil breather system. If a radiator hose suddenly blows off its water outlet, or the dipstick won’t stay put, this could be the reason. Check inside of the radiator cap to see also if there is milky buildup. 3. Black smoke indicates that the fuel is not burned properly. The internal combustion process in diesel cars requires a certain mixture of fuel and air. The ratio of fuel and air should be proper, otherwise, the mixture will be too rich, which will result in black smoke. Faulty injectors

[@rolanddunk5054]

As a retired marine engineer I cannot believe that you did not check the valve clearances…it is a must after the rockers have been removed.also I would have ground in the valves while the head was off...BUT I would have checked the injectors before I did anything else.cheers Roly 🇬🇧.

[@lukeetheridge77]

Progress is showing! Step by step day by day. Good work my friend!

[@laapulsford]

Some good advice below that is worthy of consideration. My advice is to urgently check the valve clearances as the new head gasket might be a different thickness to the old one and this will directly change the clearances of all of the valves. If this is the case, valves might be staying open or performance of the engine might be degraded. Either way, checking adjusting the valves on this engine is a 10 minute job.

this is the cleanest looking 40 year old engine i have seen .Replace the injectors and you should be fine. However ,omitting a valve job is a rookie mistake.

Good idea to put the rods in a piece of cardboard marked to Id and just poke them all through it that way if they accidentally are bumped you will not lose their location. You laid them flat and on a table or whatever and do not secure them for order you are just asking for unnecessary trouble. Keep the cylinder bores covered because you want to keep them as clean as possible no matter how much you vacuum and clean them after getting debris in them. Use rubber gloves for protection as most cleaners are not the best for your long term health. Great job and usually replace thermostat .

It may be a good idea to keep an eye on the oil level, if it starts going up, you're definitely losing fuel into the oil. The most likely location for that would be the injection pump oil seal.

[@eduardobandil4746]

Replacing the head gasket was a waste of time, if there was a issue on the gasket the coolant wont leak to the cilinder instead the compression of the cilinder would leak to the coolant sistem creating pressure inside the sistem. I'm sure that the white smoke problem was the oil level, the engine was "burning" this oil excess until it gets on the right level, if there was black smoke, u have a diesel injection problem.

[@richardsmith9872]

I am not sure if said already but in a tractor you will get white smoke when you have a hole in your cylinder wall, pressure test. We would just replace the cylinder sleeve (pack)

[@scott___1737]

I was thinking fuel injectors with the smoke but possibly oil? Definitely good to use cleaner in the fuel an add a injector fuel treatment like Hotshot or whatever you can get in Germany each time you add fuel. Good to see it's working better.

[@LearnandLive97]

The Engine runs good 👍

[@jayweb51]

My first thought with the white smoke, was due to oil present in the cylinders; thus causing the smoke. I assume that having to much oil increased the pressure in the cylinder head; causing small amounts of oil to be forced past the cylinder seals, and getting into the firing chamber.

[@iansmith6086]

13:15 depending on where you come from this white smoke might not be a problem. But if you have ever lived in Germany you would know that so many people would be getting angry about this smoke. I feel for you brother. Hope the problem can be fixed soon

[@05Petedriver]

One bit of advice I'd give is to step the torque setting up on a head. Say 30Nm, 60 Nm, then finish at 81. It allows the gasket to squish properly etc.

Hi, on my nautical license manual it’s written that black smock is a bad combustion while white smoke is the engine burning oil

[@OliverWhiteTailAlexander]

Lots of older engines will burn oil until they are at their "happy place". I fly piper archers, which can take up to 8 quarts of oil, but if you fill it to eight there's a good chance it'll burn oil until its at or around six and a half quarts. Your diesel engine probably was doing the same thing. Nothing wrong with getting some major maintenance out of the way though.

[@danparker8254]

White smoke can also mean oil getting into the intake, often from valve guides.

[@ronhatcher7734]

For Disels if the Smoke is White, its a To rich Fule Mixture, yes it can also mean water in the combustion but then you would also have white smoke when ideling with the engine. the oil removal wasnt necesary unless you seen the oil pressure drop, wich would mean your engine would have beaten the oil to a foam, like milk to schlagsahne plus dark smoke.

[@Rushinglc]

White smoke on startup would be caused by the valve seats and or seals. Oil from the top of the head is leaking past the valves and is burned off during exhaust strokes. Also, if your piston rings are worn out they will not remove the oil from the cylinders during the intake and power strokes, this residual oil is left and being burned off, I suspect this is your issue. If you suspected a head gasket, check your oil. There would be obvious signs of oil contamination with it appearing "milky" as the coolant is getting into the combustion chamber and leaking past the rings into the pan. If the smoke was black then it would make sense that there may be issues with the injector leaking, this would indicate a "rich" condition. Symptoms of this would be "hard starting", caused by the fuel pressure leaking off while the engine sits and fuel contamination in your oil.

[@normanboyes4983]

You can tell a lot by the ‘smoke’ a diesel produces: 1. Black smoke = Over fuelling for the air supplied (Rich mixture). 2. White smoke = under fuelling for the air supplied (Weak mixture). 3. Blue smoke = Lubricating oil being burned. Based on the evidence of your experience I think (2) is relevant and the system cleaner likely cleared out your injector nozzles- you got lucky. The insufficient fuel can be caused by poor injectors or incorrect fuel pump timing or indeed a failing fuel pump. In your case the high oil level was a ‘red herring’ it would never cause white smoke - only blue, but you are are right to avoid running with high oil levels it can cause frothing of the oil which lowers oil pressure and in extreme cases of very high oil level can cause the engine to ‘lock hydraulically’ as the piston descends into the crankcase. Top tip - loosen off all cylinder head nuts say two turns. Put the rocker gear and pushrods back together and turn the engine over by hand and the compression will break the seal.

[@TgWags69]

Did you smell the exhaust to determine if it smells like burning oil, diesel or antifreeze first. It would give you a good idea of what was wrong to start with.

[@jamesparker2337]

you have to check you valve stem seals, that may be what is making the smoke. They are small rubber elastomer hoods slid over each valve stem to prevent the rocker arms oil lube from running down the valve stem and into the cylinder when they are cycled in and out.

[@garyharvey3545]

I winder who came up with the idea if removing the head gasket LOL. The oil levels are usually the first thing looked at let alone not fully replacing and recalibrating top end metrics and refurbishment.
