Just get a long breaker bar & a quality T50 torx bit. (Snap=ON)

FYI head gaskets never fail on these engines so it maybe something internal that caused the failure!

That’s what I understand. That’s why I’m pulling the second head. Going to tear down to the crankshaft and at very least re-bearing the bottom end and send the heads to machine shop. Also going to get new accessories (water pump, oil cooler, etc). I’ve seen that Porsche had issues with block porosity but I don’t see where the 2.5 was an issue. Any thoughts? Also today is snap-on day I’m not going to wait a week for Cornwell.

Dllrd23, If you are planning on rebuilding the bottom end you may want to consider re-sleeving the block with the Nickies as these blocks have a tendency to wear the cylinders with an oval shape and a set of new rings will not be able to fix it..

Update. Bought 1/2” and 3/8” T50 snap on today. My dealer gave me a 3rd bit as the bit is the same in both. Broke all 3 bits and only got 5 head bolts out. 4 are still in and may be too damaged to remove with normal means. May try to drop valves down in cyl tomorrow and weld the stub to the broken t50 to the head bolt adventure it sheared flat. Any suggestions would be appreciated.

Update. Bought 3/8 and 1/2 in t50 sockets from snap on. Dealer threw in a spare bit as they both use the same one. Got 5/8 (grand total of 8/12) out. One is rounded very badly (inside). 14mm bolt extractors won’t bite on the OD. Going to try to weld a piece of 8mm Allen key about 1” long into the rounded one tomorrow. Will have to drop the valve down into the cyl to get enough access. If that doesn’t work, I’ll see if the Machine shop can cut the heads off and get the head off that way. I’ve never seen this much flex in a bolt in my life. Any additional ideas would be welcome.

Dllrd23, Do you have enough room to get a Dremel around the head?

Yes. If I let the valve drop into the cyl I will have about 189 degrees open the other side is close to the wall of the cyl head. I’ll post a pic shortly

Time to break out some good penetrant chemicals & soak overnite.
