rear main , old topic but here we go.

Hi Tom!


I also have the problem that my engine after the revision about 2000 mls ago clearly increasingly drips oil from the rear bearing. It is about 1/2 l per 200 mls at high temperature and a lot of steep hill climbing. SAE 50.

I have therefore built a larger drip pan. Clicl and drive. In it there are two ladies menstrual pads, so that the collected oil does not splash out from the airstream.


it's a compromise that works well!

Werner, what do those 2 large holes attach to? Can't quite see it in the picture.
TIA, Ken
 
Katy,
he two holes in the drip pan will be/are clipped into the lower bolt heads (between the front axle triangle) from the clutch bell housing.

Patrick,
please tell me, what means "FWIW"?

i left the car run for 1/2hr at high idle and only had a few drops of engine oil out of the bell housing hole.

i am betting the previous owner did something wrong with the transmission. probably the front bearing retainer is loose or has no gasket at the front of the case.
stupid me i should have checked the ****** while the engine was out but who would have thought that?

still going to take it for a run and see what comes out after that.

thanks

Tom,


gear oil smells different from engine oil, which can be easily distinguished.

The gearbox can be sealed very well with sealing lip bearings.

Engine oil mainly drips from the rear bearing when driving uphill. Therefore try again with the car lifted up in the front.

for sure, i did the sniff, color, feel, and taste test and it is definitely ****** oil.

thank you

I have heard of oil coming out around the back of the camshaft opening in the block before.

that would be a gasket problem behind the bell housing. i used a bit of sealer around the cam journal opening when i mated up the bell housing to the engine block.

A NOTE ON THAT-- i watched a youtube video where the guy was adding shims at that point between the engine and bell housing..You shouldn't do that as the shims will leave a space where the oil can seep out of that journal.
i would guess if you wanted to shim it there use gasket material and make sure it covers the cam journal.

don't have that problem.

thanks

I'm not sure what video you are referring to, but shims between the bell housing and block are added to align the bell housing to the crankshaft flange.

yes but NOT at the centre mounting flange beside the camshaft journal. it will leave a gap and leak.
shims are added at the top.
if i were to need to shim the bell housing at the centre flange i would add a second gasket there so it would seal.

the transmission is out now with just the engine sitting in the frame.
i ran the engine for an hour at above idle speed. no oil came out the rear main.

the inside of the bell housing is soaked with ****** oil. i can see the trail of where the oil ran down from where the shifter tower mates with the bell housing. on further inspection i found the shift tower gasket out of place and the gasket between the bell housing ripped, and has a gap.
no oil appears to be coming from the front bearing retainer.
i think new gaskets and a bit of sealer should make it good.

now onto some transmission repairs.
who ever put it together broke an inner bolt boss and the pc went into the cluster gear, destroyed the cluster and 2nd high slider gear.

haha i guess we can disregard the question about the rear main. and get ready for other questions.

thanks everyone for helping me here.

Just as it is a good idea to run the engine oil a half quart low, it is also a good idea to only fill the trans oil until you can stick your finger in the fill hole and touch the oil.

It is common fill the trans until it runs out the fill hole. That is overfilling and it will run out the main shaft onto the clutch disc and out the hole with the cotter pin.

It is especially bad when you park facing down hill.

Just a thought...Mitchell makes the 'Real Deal Transmission Seal' that will stop oil coming out of the front of the transmission....might want to look on their web site or call them...it actually works and you can install it by taking the cover off the bell housing inside the cab, under the floor boards and sliding it in and it takes two bolts...not real easy but worth the effort. I stuffed a rag in first so if I dropped a bolt, it could not go to the bottom of the transmission...Ernie in Arizona...
