thats when i started ti laugh at the guy:Dand told my buddy to leave:angry-smiley-038:

its ok it just gave me an excuse to build it up bigger:drink:
i was in a rush trying to get it ready for the TF200 but wiped it out. Took my time the second time and she has run strong ever since.

The boom was caused by the zz502 heads i put on dropping a valve which the tech at gm told me they have been having that problem:eek:atleast they replaced the head free.

No. But some or them are. You wouldn't believe some of the idiots I've interviewed in my lifetime. Then, there are some guys out there who can fix ANYTHING. Ya just gotta find them.

I think a timesert would be a better fix for that problem, heli-coil may have sealing issues in that application

I'm curious - was this a stock engine or was he running a power programmer on it?

More than likely stock, Fords do this.

Possibly. Until Timserts came about, helicoiling was the only way, has worked for lots of fixes.

My dad took his Expedition to a muffler shop for a cat-back system. They told him his manifold studs were rotten and in order to do the job, they'd have to pull the heads as the manifold-to-head bolts were corroded badly as well. I had it towed to my nephew who drilled the studs out and bolted the crossover in. Their quote $2500. His labor- 2 hours.

They catch lots of people every day.

Don't know if it's still the case, but they were the only thing approved for Mercedes head bolt repairs back when I was wrenching on them. Never had one fail. Helicoils are very iffy for spark plug repairs IMHO

I agree. Less room for an imperfect repair, Timeserts are better, but they're not as easily found at your local parts house.
