Thread: To Stop-leak or Not to Stop-leak

A few Q's .....

If you paid particular attention to re-fixing this seal .... Was there anything obvious about any defects in this area?

What was the mechanics opinion?

What oil brand / grade are you using?


Mike

Sorry I'm so late getting back Mike, and thanks for your reply
I had a house full of visitors.

I had a good look at the whole facings of where the housing meets the back of the block, looking for burls or scratches but all looks good, as it should be with a reco/new short block.

My mechanic thought it may be T seal - only one way to find out

I'm using Penrite HPR 5w40 oil. I hope this is not thin.

I did a bit more reading a nd realise the stop leak stuff works by swelling seals, not blocking gaps. I think I'll do like a lot of LR owners do and see it as acceptable weepage.

Cheers

Mark, Stop-Leak is a temporary fix and you will continue having issues. I don't tolerate poor workmanship – ask yourself the question, why is the seal leaking in a rebuild short motor? – is it something I did causing this? If you weren’t the cause, it is up to the supplier of the donk to rectify any problems under warranty. Unfortunately, if you assembled the rest of the motor and installed it into the vehicle yourself then you are responsible for removing it and taking it back to your supplier for diagnosis and repair.

These are my thoughts also .... By any chance ... did you check the sump for warpage??

why 5w40 in a 300tdi? A td5 yes but?

I was leaving that for the "Brains trust" to jump on that one

I was wondering if it is synthetic or non ... ect

Would have to be syn,I would think.

Gidday to All,
and thanks to all for your responses.

I'll definitely give the stop leak a miss, and as I put the rear seal and motor in, it'll be up to me to pull it out and fix. (will do this before the novelty wears off!)
I did check the sump for warpage using a flat surface and also a steel ruler, but as I'm a novice to major engine rebuild, I might have missed something. I take it that the slightest amount of warpage will cause problems.
I see comments about synthetic oil. The Penrite HPR5 5w40 is a semi synthetic.
Is there a problem using this in a 300tdi and what oil would you recommend?

Cheers
Mark (still on the learning curve)
