Default Re: oil leak behind the accessory belt & pulleys

I've used 2 o'rings on leaks.The 1st one a tight fit & a slightly larger one to compress a larger area.

Default Re: oil leak behind the accessory belt & pulleys

I did mine today - it was reasonably easy, and even though i didn't have the correct O ring, I had 2 that were almost right - one ID matched but OD was a fraction small, and one OD matched but ID was a fraction large, so I used both with the larger one towards the bolt head. i also used some high temp silicon on the threads so it should stop the leak. For the record, the old o ring was brittle, and had a crack in it.

I degreased and high pressure washed the side and front of the motor, and thoroughly cleaned the alternator too, so hopefully it should breeze through rego once I take it over the pits to transfer it to my name. All up, this took around 1 hour.

Run it hot, check for residue in electrics, check manifold gasket, might be worth giving all engine loom connections a crc or similar water disperse, yeah. so I'd crc the loom connections first , then give the engine a water rinse, avoid the inlet manifold gasket, take it for a drive to heat and evaporate water, then go from there. Once its all hot and dry trying flipping it over to gas.
It was the inlet manifold gasket. Pr!ck of a job but 4 hours later all done and running well again. I think it's leaking oil from the front of the engine. Looks like it's from the long bolt on the power steering bracket even though i gasket gooed it so might have to take it out again and goo it more.

It'll be the timing chain tensioner cap bolt, that is on the side of the block, near and under the power steering pump bracket. It's a black bolt head and takes a 14mm socket (the others around it are 13mm/10mm). the o ring probably needs replacing, and the bolt itself will need new silicon to seal it properly.

Car is idling at 2000 rpm on petrol and backfired and won't run properly on gas, i did degrease and wash the engine so that may be the cause also but just want to rule out the tensioner.
Just did that JC as above. The problem in the last paragraph was because of stuffed inlet manifold gasket, i thought i did something wrong doing the tensioner but it just so happened the gasket decided to give up at the same time. All good now, except for the leak out of the long bracket bolt.

I had to clean up the Mitsubishi alternator after fixing the leaking brake pipe connector above it.But there hasn't been any alternator trouble.Is the starter motor also a Mitsubishi product?

If youve done inlet manifold gasket. the rear bottom is a bugger to do up fully, and the gasket can shrink over the next few days / weeks depending on use, so go over them again in a week, and 2 weeks etc. as the fibre gasket shrinks before being settled, a bugger really you go out 2 weeks later and the bolts are loose. lol p.s. you probably should have done a few things while the manifold was off, hahahaa save you trouble later. ie everything under the manifold jokes.

Default Re: oil leak behind the accessory belt & pulleys

the large thread on the timing chain tensioner leaks, ive done a few. pretty simple job just clean and goo the thread but let it cure properly before running. All pretty simple, just do the thread up by the to small holes, with a hammer and a screwdriver, doesnt have to be overly tight, just let the goo set, and make sure tensioner is in properly locked position, ive pulled mine out to many times to count, or the actual timing chain cover gasket can go as mine did, so just cleaned dried, gooed the **** out of it let it cure properly, no problems since.

CHEERS for the Heads Up
Only just found this thread again.

Ended up finding the leak, it was the long bolt that holds the power steer pump to the engine. (Must go into an oil capillary or something).

Fix ... some plumbers tape around the thread and added some gorilla snot to the top of the thread as I inserted it while I tightened it back up.

Thanks again guys.

Did you just seal it on the outside and not take it off? If yes what did you use please.

Sorry about the thread mine but good threads like this one do go on & on, hey UK!

I just had the timing chain tensioner leak on my xr6 engine, using this thread helped me heaps in fixing the leak. Thanks to all who contributed their time & info to this very helpful thread.

At first i thought it was leaking from somewhere else so tightened & cleaned everything up took my kids to school yesterday then checked & you guessed it a little stream of Castrol Edge on the engine crossmember again!

In the end, mine was only a loose timing chain tensioner mechanism which i unscrewed out a bit & applied some gasket goo then i tightened it back up securely (thanks for the tip UK). I also applied some goo to the last long bolt under the vct pulley on the last bracket to come off just in case it leaked there too.

Left it overnight then today took my xr6 for a drive & the leak is no more for good i hope. I think the mechanism was loose only for a little while, so hopefully no brittle o rings fingers crossed.

Hope thats the end of that, now to clean up my garage floor oil stains..

cheers, Maka

I have oil coming out of the bottom long bolt that holds the power steering bracket on as well.

Have tried sealant and also teflon tape, but still seeps out from behind the bottom of the bolt. Most annoying leak ever... Does anyone have any more tips for fixing this, as it's driving me crazy!

Replaced seals on tensioner on my au and still leaked. Plenty of sealant on long bolt stopped the leak. Make sure the sealant you used is oil resistant. Not sure what I used, just that it was black or grey in color.
