helicoil engine case

[porscheturbo]

hi, went to put the cylinder head on my boxster today and the very first bolt pulled out of the case( at only 20 foot lbs.) :angry:

has anyone helicoiled the case on this board? is there a special kit for the porsche. I have helicoiled many holes but never a head bolt, especially a 9 inch head bolt. any advice, tips,etc is appreciated.

Bizzare. Long head bolts (or studs) sure, old bugs had heads falling off all the time. Helicoils were on everyone’s service record. Porsche, dunno… but can’t imagine why not. I’d be concerned as to why.

On the air cooled engines they use timeserts, because helicoils can pull out. I have seen engines with the heads off at the dealership, but I never asked if they had one with a pulled out head bolt.

I do not know any US shops rebuilding the M96 engine. There are several UK shops that do.

The one that comes to mind is Hartech (Barry Hart). http://www.hartech.org/index.html Hartech himself is on the UK board Pistonheads. Here is a link to one of his messages if you want to find him. http://www.pistonheads.com/gassing/topic.a...=0&t=471313

Pelican has an engine rebuilding forum, but it is air cooled. You could also ask there but I doubt if they have experience with water cooled engines. http://forums.pelicanparts.com/forumdisplay.php?f=257

Autofarm is another UK shop. http://www.autofarm.co.uk/engines/water_cooled

thank so so much for the help. i have sent out a bunch of emails and will let you know the results.

is this the same 98 motor you picked up as blown? I hope not, turns out most of those motors had cylinder sleees that would slip.

any way timesert is the way to go, you are threading in a steel sleev with new threads for the bolt.

also did you ever find a timing kit, we put one together.
