Matt, that was brilliant. The whole idea of a "..fraction of the cost..." is genus. A fraction where the the numerator is many times a multiple of the denominator is a "..is too, a legit fraction.." . You must be an engineer, because you clearly have an engineer's understanding of mathematics.

[@TheFrozen1313]

This was clearly the most bugdet friendly way forward, I wouldn't expect anything less!

[@fredfarnackle5455]

Oh dear... I suggest that you look at a 1950's British motorcycle dry sump system. It is a reciprocating double pump driven by a crankshaft cam, the large bore pump is the scavenge, the smaller one is feed from the tank (located higher than the engine) to the engine. Simple but effective. The sump in those engines was truly dry. It also has the added advantage of keeping the oil cooler.

[@allareasindex7984]

Would it have been easier/cheaper to do an electric scavenging pumps? Redundancy (2 or 3 separately powered pumps) + put some magnetic encoders and flow meters on them to flash a big red light at you if they stop spinning. I would also suggest some sort of oil level sensor in the tank.

[@MeatPoPsiclez]

Most of the electric pumps I've seen suggested for this purpose (for dry sumps and remote mount turbos) are just relabeled transfer pumps, and aren't designed to move oil at operating temperature and will eventually fail.. Though I'd be very interested to see some are actually suitable!

[@h-j.k.8971]

Yes yes I enjoyed your video, mostly beause I have made a few dry sumps myself. A few were made by the engine itself by being old and using all the oil in the wet sump until it was a dry sump, others were made the easy way such as throwing too much money at the project, which looks much like youre currantly doing, others by combining used oil pumps simmilar to what you had in mind until you chickened out because they had no bearings etc. Just for the records, these pumps work fine when used as scavenge pumps as the never run completely dry.

[@frosthoe]

Did the same with hydraulic scavenge pumps and a 2 gallon reservoir, feeding a 160psi HV oil pump. I used this on a 74 Volvo rally car build in the mid 1980's. I actually stopped using the Volvo redblock 2.0L and went with a full tilt 305 Rpm build, with the homemade drysump. In hindsight I believe I killed the Redblocks from my own errors and inexperience back then in the 80's. I kept melting pistons...but it never once threw a rod or hurt the crank. Those Reds are F1 quality castings!

Not real money of course. Thats already gone. :D

[@thesetruths1404]

Great video. Just what I was looking for. I have a 98 Pathfinder 3.3L with a similar oil pump. It was an elderly couple's for 20 years. I don't think they used it much. Low miles, 6,000 a year average, and likely wasn't driven hard ever. I think they let oil sit in it and maybe their mechanic put snake oil in it as a sales pitch. There was gummy honey-colored stuff on the refill cap. Something is causing this Pathfinder to knock at startup for 3-4 seconds and then between 1,800 and 3,300 RPM. If coasting between 1800 and 3300, it ceases. I think I caught rod bearing wear early and I replaced them. And checked the mains. Mains were good. Two rods had mild wear. No slack or slope in anything. Metal flakes stopped appearing. But still the knock between those RPM. It runs perfectly, otherwise. And the body and interior is like new. So it's a nice one I'd like to keep long-term. What do you think about this idea? If the oil isn't changed well can the valve system in the pump stick or malfunction and cause oil pressure to be insufficient? The pressure is 100% consistently poor at startup for 3 seconds and under load between 1800 to 3300 RPM. Makes no sense, this loss of pressure at fixed time, other than faulty pump. I know there is also a pan gasket leak at the front and back. I thinned the oil as an experiment to see if pressure/noise changed and oil began quickly dripping from both ends of the oil pan when it was at warm idle. I thinned the oil 50% with motor flush, which is basically kerosene. I drained out two quarts and put in 2 quarts cleaner. So I have to pull the pan anyways to fix those leaks, so might as well pull inspect and replace the pump as well. Also have to check timing as well and swap all those parts as their age is unknown. The pressure problem was present before the leaks were noted. So the big leaks are new and the problem is the exact same. Do you know of a good oil pump replacement video of my motor or very similar? I found a timing kit one, but no oil pump.

[@williamhustonrn6160]

I know you already spent money fixing your issue, but i have a Locost 7 with R1 engine and the way i fixed the oiling issue was very different and a fraction of the cost you spent. I used a section of PVC in the center where the pickup pulled oil from to create a skinny cylinder area in the center of the oil pan for the oil pump to pickup oil from, then using silicone i poured in the oil pan filling all the area around the PVC pipe up to the top of the oil pan mating surface. This leaves the only area for oil to sit inside the oil pan is inside that cylinder cavity the PVC pipe left behind. Then i removed the PVC pipe and trimmed the silicone to smoothen out any defects from the pour. Then on the side that is facing the front of the car i welded in a 1 inch bung, which i have copper tubing connected to wrapped around the bottom of the engine at the level of the OEM pan oil level giving me capacity. The engine's oil pump pulls oil from the skinny cylinder void in the oil pan to feed the engine. The oil draining back into the oil pan is forced to drain into that small cavity in the center of the oil pan since the silicone is filling the rest of the oil pan area. The excess oil via gravity drains into the copper pipe to give the engine oil capacity, which gravity is constantly trying to drain back into the oil pan. When the engine is turned off the oil drains into the copper pipe to maintain the stock oil level. I placed the bung for the spillover point at the side of the engine facing the front of the car, so under acceleration the oil in the copper pipe is given advantage to drain into the oil pan easier. This has worked perfectly for me. I did have to relocate the drain plug since silicone covered the original one. The way i change oil and check oil level is purely by ball valve. On the copper tubing that wraps around the bottom of the engine. I have a bracket holding the end of that tubing at the level the oil level needs to be at, so i just open that ball valve and pour oil into the engine and when it starts dripping out of the ball valve its at level and i shut it off to seal the oil system.

[@danixsc]

Pretty interesting: as motorcycle engines are designed to ALWAYS have oil at the bottom in the intended use case (not doing wheelies), when you put them in a car, which instead of leaning (which applies centripete force to the oil so it sticks to the bottom no matter how much you're leaning), just applies the centripete force to the side and therefore you starve oil from the pump and there you go, destroyed engine. Never though about that but makes sense.

[@SuperYellowsubmarin]

That was might fun ! Doing the exact same kind of stupid stuff on an aircraft engine (dry sump, plus oil cooler, ...) and I can definitely relate. An fittings are expensive but think that for a DIYer they are very valuable because they are so modular. you can always find an adapter or fitting that will work for you and mate with the other fittings. Plus when you have a lathe and mill, it is quite easy to make your very own special adapters when all else fails !

Matt, Nice start on a dry sump, couple of comments, 1. Don't use NPT [National Pipe Thread] fittings, they leak, vibrate out and it looks like you tapped them to deep as the fittings look loose. 2. Electric water pumps are less than optimum, there is a rule of thumb that the water flow should be 10 gpm/100 hp so you need at least 20 gpm but electric pumps are rated at zero outlet pressure so any pressure required to push the water through the engine will reduce the actual amount of water going through the engine. I see you selected a Davis Craig unit which is good, as they are the only water pump people I have found that provide flow/pressure charts for their pumps so I would use that to select the pump. I will be interested to see your oil tank design, do you plant to fab yourself or buy one?

[@SuperfastMatt]

I haven’t had any problems with NPT fittings since I started using Loctite 545. I didn’t show the fittings fully tightened with Loctite in the video, but that’s how they’re in there now. I’ll probably fabricate a oil reservoir, with some help from SendCutSend.

The DIY projects usually cost me what it would cost me to pay somebody to do it, except I do it all myself and the machines and tools get paid for with the project budget. I look at it like "sweat equity" to build a dream shop full of tools and equipment. Plus I learn a whole lot along the way, and I can build anything I want in my shop now. So yeah, think of it as a 40yr plan to be mechanically and technically independent by the time you're too old and decrepit to have the will and energy to do anything. LOL

For about 2 weeks I've been binge watching all of your videos. Thank you

Having done it many times in my life, designing a properly-functioning dry sump oil tank is one of THE most difficult engineering tasks in building a racing vehicle. The tank has to collect, cool, and remove ALL of the air from the returning oil or it will quickly be identified as THE part that most contributed to the destruction of the engine it's attached to!!

Engineers always know the best way to do things.

FSAE cars have been doing both of these solutions for many years. I'm glad to see this video though, really great stuff.

I've watched this vid a few times now and it got me thinking about accumulators again. I've used oil accumulators in the past in streetcars where I couldn't use a deep or widened pan(68 bigblock Dart, you feel me?), I've wondered if the problem of the rapid drop in pressure as the oil is pushed out of the cylinder could be dealt with by having the outlet from the accumulator in the oilpump pickup itself where the oil would be immediately pressurized by the pump instead of introducing the oil into the engine downstream from the pump. It doesn't address the issue of the finite amount of oil in the cylinder but you would have more reliable pressure as long as it lasted. I can think of a couple of "simple" ways to route the line to the pickup that are something less than a colossal p.i.t.d. but never really needed more than tthe accumulator could give me so never explored the idea. I have a Lowcost w Mazda 12a power that I've been building since the 2nd Bush administration though and the idea of a big frantic bike engine sometimes seems like a good way to delay completion till the NEXT Bush administration so I started thinking about it again. How many seconds of full pressure oil do you think would have been necessary to avoid blowing up the mill you blew up? All hail

How are you going to control the oil level in the engine? I believe you need the oil pump pulling oil straight from the reservoir. If you just have a line from the reservoir to the engine the oil level will balance out between the two and could blow the engine. Check out the dry sump system on a C6 Corvette Z06 for method of operation. Z06 engines are blown up by quick change oil operations that put 8 quarts of oil in the engine rather than the dry sump tank. The pan volume is so small even 5 quarts in the engine would be dangerous, I think. Great idea, good luck.

Fantastic, as usual.... Oil pressure sensor, check the data/instruction sheet!!! Fitted a similar sensor for keeping an eye on fuel pressure (had a spare hole in the dash for a gauge...🙄), drilled and tapped the fuel rail, stood back to admire, just so happened to notice the instructions that came with the sender, and says DO NOT MOUNT DIRECTLY ON ENGINE, VIBRATION WILL DAMAGE THE UNIT..... 'jsmcortina' of megasquirt fame, has recently damaged an lm7 through low oil pressure (but no oil pressure warning light), so there's code now, to bring on the oil warning light, depending on pressure vs rpm, although, maybe why you've fitted the sensor, rather than low pressure switch......🙄🤔

Making it yourself and you’re getting it little more expensive than from the store, and little bit crappier. Awesome video!

I was cheering for you and your economic goal and was shocked 😮 you went over budget. Totally worth it! Great project!
