Hi im going to put a new oil cooler on my car 2.5 v6 on the bill for work done in the past it says 'oil filter housing thread stripped pipe refitted with bonding agent and tested ok' is this common or have they overtightened the pipe
Thanks all

The threads in the oil pump not the pipe

Oh sorry, its normal for the cooler threads to strip but cant say i have seen the housing threads strip unless cross threaded.

Ok cheers if they have stripped do you know if its possible to have them tapped

TBH, if its not leaking i would leave it alone, its a big job to change the oil pump if things go wrong.

Hopefully you can just release the cooler unions without issue but these can corroded and not undo without twisting the pipe work.

Any reason why you're changing the cooler?

Its blocked up with k seal and i have the water side of the cooler bypassed at the moment. I have a new cooler with new pipes

If the pipes are ok, i would just replace the cooler to save disturbing the housing connections.

Thanks i'll try taking them off from cooler first it was just i heard that the threads can strip on the pipe when you undo them from the cooler so thats why i got new pipes.

Normally the other way around, the treads on the aluminium cooler strip, the pipe unions are steal.
