Thread: Broken manifold studs, AGAIN

After 9 years and 95000km my studs went, four of them and not being all that handy with such work went to Graham Coopers for the job.

They expressly advised not to use the modification suggested by redback as it weakens the manifold, so that instead of breaking studs you end up with a cracked manifold, which is way more expensive to replace than repairing studs,

choose wisely.

After my experience with Coopers I wouldn't believe a word they said. Total incompetence is all I can say about their service! I had a perfectly serviceable Td5, albeit with a blown head gasket, and somehow ALL 5 injectors (yes you read right) mysteriously stopped working while it was in their hands. They have no idea what happened "it just happens sometimes" however after exhaustive research it only seems to happen at Coopers. I wouldn't take my vehicle back to Coopers if they were the last place on earth. Needless to say I had to foot the bill for 5 reconditioned injectors.

As for them trying to tell you that this mod would cause your manifold to crack well that seems to me that what they are really saying is, if you solve this problem we won't be able to charge you to replace your studs ever again!

I agree 100% with Phil, cast manifolds are easily repaired and would be done so much cheaper than paying Coopers to replace your studs every now and again! This mod would not effect the life of your manifold if done correctly.

I'll put money on them having put the head on the bench and damaged the injectors that way.
