buying and fitting an oil cooler

[djinuk]

ok , i hvae a superstomp 140,

i purchased a oil cooler and fitting place from wpb, ive fitted it to the side of the block using black engine sealant, aswell as oil lines with the copper washers etc.. i only left the bike a few minuites and when i started it , it sprung a leak, last night i wiped all the sealant off and did it again, this time leaving the sealant to cure, tonight i will try it , but really my question is , should it be ok to use a sealant on these engines or should i really be trying to find a cardboard gasket.

I work primarilly on high powered turbo cars and sealant is the standard approach for these kind of things, however im new to bikes.

On the head take off plate use two copper washers either side of the banjo connector and that should be fine. No need for sealants.

He's talking about sealing the take off plate to the side of the head.

I've found that without gaskets, these engines just dont seal up. I've used liquid/instant gasket around the base of the barrel before, and it's still chucked out oil.

very true also i find that the copper washers are only good for one time nip up only as being soft they do there job once 2nd time you will find they weep and if you over tighten you will strip a thread unless you heat the washer up but would rarher use a new copper washer as pennys dont know what pressure that oil cooler is under but know its got some !!!

There should be a gasket under the head take off plate of course and if that the leak point then a new gasket needs to be made or bought.

The copper seals are reuseable and a bit of ptfe can work if they are in poor nick.

Pressures are quite low as the crank has a breather.
