Holy crap oil leak!

[85silverna]

I am not familiar with parts locations on my 85 mr2. The oil is pouring out from the exhaust side of the motor, somewhere under the distributor. I have established that the dizzy does have a very,very small leak on the top side. What makes me worried is that the flow is higher that I would think could come from the distributor.The oil is coming out roughly as fast as when you pull the drain plug during an oil change. Basically I have not gotten under the car but I was wondering where the oil pump and lines are and go, as well as what else besides the oil filter port could leak there that way.

Also I suppose I should mention that the car was running pretty rough lately, like it had a miss. I did plugs and wires, cap and rotor, and it fixed most of the problem, I figure that the timing is off, but could my leak and the rough running be related? (also not that with the miss, severe backfiring and power loss was noted until 4,300 rpms, with the t-vis kicking in.)

You could degrease the whole engine, put some dye in the oil and use a black light to find out exactly where the leak is coming from. And I know on my MKII the oil pump is driven by the timing belt, twards the bottom rear passenger side of the engine. Might be the same for the MKI, but not 100% sure.

I dont think its timing belt driven, the guy I bought the car from did the head gasket, and all i remember the timing belt running were the two cam gears and the crank...


edit: ah crap, while I'm here, where is the freaking tranny dipstick or fill hole or whatever? I'm tired of rooting around my engine compartment to find it!

The oil pump is crank driven on the timing end of the engine. The crank is shaped and the oil pump slips over it.

On the later cars there is an oil cooler that runs to a water pipe that runs some of the oil pressure through it. The pipe is on the firewall and the line comes out from the filter and returns to the sump. if it has a cooler check the lines are not split or loose cause that would have the sorta flow your talking about.

damn long day at work today started at 6am and left at 1:10 this morning. plan to look under the car today around 10 or 11, not lookin forward to pushing the car around but im certainly not running it, im not wasting any more fresh oil. Same as always, dix one FU%@#ing thing that breaks, and ruin something else while fixing it, or during the test drive something is certain to go. Gah... I still love cars anyway...

Don't know about autos but on the manuals the fill hole is on the front (firewall) side of the gearbox, you will need to be underneath to see it. It is a 24mm bolt that is kinda flat looking. undo it and if oil runs out then it is full (if you want to keep the floor clean quickly put it back in).

the rubber oil lines going from the motor to the oil cooler ??

[85silverna]

its an 85... I thought oil coolers came only on the later year mr2 mkIs

[nitrate]

no they all have a cheep one built in to the coolant lines. there are 2 rubber hoses going to one of the cooling lines on the pas side fire wall

[85silverna]

found it, lin from oil filter housing to the oil cooler was toast, threw some 3/8 fuel line on there for now, at least its driveable. no one answered my other question though. Where is the trans fill neck for this car, 85 5 speed, I want to try this synchromesh everyone is raving about. I'm just used to big GM cars where it is stupid easy to find.

[nitrate]

on the back of the trany kinda on the side back twords the bumber/oil pan is 2 fill plaugs. if i remeber right the top is the fill the lower is a drain.

How is that fuel line holding out?

I've fixed just about every possible leak spot on the bottom half of the block, and the oil cooler line is the last thing to do, but toyota wants over $200 for the pair of rubber oil cooler lines, **** that. I know i should get something proper put in, but a fuel line should be able to handle some pressure right? And it isn't that hot in there.

Another thing is that i was told by some guy that i should just bypass the oil cooler.

$200 for some rubber hoses, geez! That's like the gasket for the rear tailights they wanted $22 for. I said screw that and used some gasket maker, problem solved.

But how did the gas lines work for you?

Luckily it doesn't look like i'll have to replace the cooler lines, but still curious how they held up.

go buy some proper oil cooler line asap, doesn't have to be from toyota, just make sure its made for handling oil and have high temp rating, oil will attacks and softens the rubber on fuel lines.

[ebouwman]

good information HoLun

I suggest using some push-lock hose, like what you can get from Jegs. It's cheap, comes in all sorts of sizes and colors, and is made to handle heat, fuel and oil. I used it for my oil cooler system in my supra turbo.
