Nissan Patrol TD42 valve set adjustment

[@Jonesey2625]

Great videos mate, everything you’ve done to the GQ so far has been explained very well and I’m sure it’ll help a lot of new people out there just getting into Patrols

[@downtheshedwithbyron]

Thanks bro it's all about helping out a mate dirty thumbs up👍

[@nikkivale]

They way you lay out this video is perfect m8. Just the right amount of time on each step with really clear pictures and instruction.

[@downtheshedwithbyron]

Thankyou very much. Gives confidence to have a go!

[@downtheshedwithbyron]

Good on ya mate take your time you'll be fine 👍

[@rodneytaylor6261]

If your like me and don't have a 41mm socket ...put it in 5th gear and push the car forward .....removing spark plugs helps if petrol...if its a auto go buy a socket....

[@downtheshedwithbyron]

Yeah thats a cool idea mate Dirty thumbs up 👍

[@marco3499]

Thanks mate.... Better than Haynes manual 👍

[@downtheshedwithbyron]

Cheers bro I look bac at that video now and think how could I make it better again haha

[@Nick-sd7um]

A really helpful video for me mate thank you. I want to have a crack at this myself but the only thing I was hoping you could clarify for me is visually confirming the TDC part. From what I understand (your vid and workshop manual) cylinder 1 will be at TDC when the mark on the crank pulley and timing cover are aligned with one another which seems straightforward. My question is just about visually confirming TDC for adjusting 1, 2, 4, 5, 8 & 9. My understanding is that you can visually tell you're at TDC to adjust the first sequence of valves (I mentioned above) based on two things: 1. The mark on the crankshaft pulley and timing cover are aligned, and 2. Valves 1 & 2 will have clearance I.e. both valves of cylinder 1 will be closing and the inlet of cylinder 6 will be starting to open. After that first sequence is done, rotate the crankshaft pulley 360 and align the marks and then repeat for the remaining valves. Does it matter if you rotate clock wise or anti clock wise? Lastly and before starting the car, do you need to rotate the crankshaft pulley back to TDC (cylinder 1) or back to its original position before you even rotated it at all? Or is it fine to start no matter where you rotate the crankshaft pulley? Sorry for all the questions

[@downtheshedwithbyron]

Gday mate I would still continue to rotate the engine clock wise and it will be fine to start after the jobs done. 👍

No dramas bro

I found it was possible to rotate the engine by a 19mm spanner on the power steering pulley

[@downtheshedwithbyron]

Yeah sweet bro I was to scared of over tighting it haha

so when i bang the rocker cover on what size hammer should i use? also i followed you home from the airport. i will come round now and live in your garage....

[@downtheshedwithbyron]

Darren tell you what you bring me a carton of lemon squash around and I'll give you a hand save you put a hole in that rocker cover take it easy mate 👍

[@Liamd2001]

Splendid vid mate, keep more coming 👍

[@jimonhisown]

the term rocking relates to valve overlap on the companion cylinder. ie if you have the engine at TDC No1 then its companion cylinders valves will be rocking. Ex valve closing, intake opening in DOR. Rotate engine counterclockwise inlet closing exhaust opening this is what we call the rock or valves rocking due to the motion of the rocker arms. You never set the gap on rocking valves because the valves are not fully closed. This is a common mistake and misuse of the terminology.

[@downtheshedwithbyron]

Cheers bro

[@MichealDavis-z7k]

Hey bro the air breather on the end of the engine at the top oil started to come out of it and wondering if u know how to fix it

[@downtheshedwithbyron]

Hey mate pull the rocker cover off and from memory these screws that hold the breather in pull that apart and give it clean Next id be checking your blow by

[@katherinecastro7850]

Hi, from Panama my uncle wants to know where exactly he needs to put the marks since he doesnt speak Spanish I am just trying to help him but he says he doesnt understand where there should be a sencond mark.? I appreciate your answer.

[@downtheshedwithbyron]

Hello The first mark on the harmonic balancer is to adjust fuel pump The second 1 is TDC On the timing case these a make to line it up to. I hope this helps you 👍

[@livingadamman7994]

Cheers mate...!

[@mikehunt5626]

Hey Byron, just to confirm, you said TDC with 1-2 rocking, that is clear but are you saying that while it is still on TDC after adjusting 1-2 rockers I then do 4-5 and 8-9 without turning the crank? Then I crank it 360Deg and do 3 6 7 10 11 12? love the vids buddy.

[@downtheshedwithbyron]

Gday mate Yeah thats right ive got to do this job this week Giving my old patrol a birthday haha take it easy mate 👍

[@turkkiq]

Very clear and nice video 👌🏽, should I follow same steps for tb42?

[@downtheshedwithbyron]

Gday mate Yeah mate but just double check clearance but im pretty sure they are the same

[@turkkiq]

@@downtheshedwithbyron Thanks a lot 👍🏽

[@spoofking91]

Hey mate! Just checking, does the engine must be hot when adjusting the valve clearances? Also, is it .35mm on all 12 valves on both cylinder 1 top dead centre and also 6 cylinder TDC? Thanks mate

[@downtheshedwithbyron]

Just warm bro Yeah about .35 all valves

[@willgeuan6871]

How do u go about replacing rocker arms. Previous owner had done valve clearance and nipped up way too tight. Fatigued over time and broke a rocker under hand tightening.

[@downtheshedwithbyron]

Hey mate i haven't changed 1 before on a td42 but from looking at my spare engine you should be about the remove the assembly then slide the rocker of as needed If you need any more help ill have a play with it next week and let you know 👍

[@willgeuan6871]

@@downtheshedwithbyron thanks for the quick reply mate, I’ve had a good look and It just seems like a couple nuts in between the rocker arms and it all should pop off.

Ill see what i can do tomorrow bro and ill let you know

Just adjusted mine to .35 but still just as noisy... worn rocker arms or shaft?

[@spoofking91]

Excuse my ignorance mate, but why would it be necessary to adjust your valves frequently?

[@downtheshedwithbyron]

G'day mate just referring to the workshop manual or if you're doing Heavy Towing or hard four-wheel driving all the time and all you'll be doing is checking them. I've been across the Nullarbor and back and probably done another 20000+ since I last done them and only had to just a couple. Hope this helps you mate 👍

[@spoofking91]

Down the shed with Byron Legend, thanks mate! Silly question but if you don’t adjust the valves frequently on a TD do you run the risk of your valves hitting the pistons? Or is that more so if your motor is incorrectly timed? Hope the old girl went well on the Nollarboor 👍🏼
