Its been over 10 years to get my tool box to this point, lots of searching for deals along the way, that's for sure. The tools see the most use on the 944, which is not dirty at all, so the tools keep themselves pretty clean without too much effort from me, thank God.

not lending them out keeps them clean too. Ive given away complete socket sets cause a borrower returns them dirty and I cant stand the sight of them. I learned to keep a cheap set of tools lying around for those dirty bastids!!!

Nothing worse than filthy sockets, good idea keeping cheap lenders around.

OK, I got into the oily bits last night. Here's the cam box assembly ready for removal:



And gone...







Here's the lifters in their oil bath where they'll hang out for the winter until everything goes back together:



Next step is to take the head off. I'm going to let everything sit for a week. Pulling the cam box lets lots of oil run down the exhaust side of the engine, despite my best efforts to be clean. I want all the drips to hit the ground before I get under there to loosen the headers.

Tools for the work last night:



Lots of 3/8 stuff, including one of my favorite ratchets, my classic V code Craftsman 3/8 long handle flex head. The 4 lb sledge was for tapping the allen socket to wake up the bolts holding the cam box to the head. The factory tool kit that came with the car provided the long 6 mm allen key to get into the cam box at the hidden top side bolts. Porsche even thought to put a hole in the spark plug tool to turn the allen key. Great stuff.

Alright, no actual work to update but I did pickup my "new" oil cooler from West Edmonton Radiator today. Its been flushed, pressure tested, cleaned and some fins straightened, all for $26. Can't complain about that.

The stock oil cooler on the car is considered OK for street duty and barely adequate for track duty, so its time for an upgrade. The oil thermostat for the cooler is built into the stock sending unit, so this bigger cooler won't delay warmup. It came from another 944 Turbo owner in Florida, I figure if it handled the heat down there it should work up here too. It was originally from an RX-7, the end tank is modified, it is a relatively common modification for our cars - a budget way to get a bigger cooler.

So, some good progress from the weekend, the head is off. It really didn't look like the engine had ever been opened, I'm going to guess the last person to look in here was called Fritz. The head gasket was definitely past its best:



Here are the pistons, 4 through 1, back of the engine to the front.

You can see some damp on #4 at the back of the engine. It wasn't oil as it was evaporated by the morning, so I'm guessing the coolant pressure issues I saw at my last event with the PCA were related to the head gasket. That cylinder suffers head gasket failures the most due to heat issues back there. When I have the head refreshed I'll have a steam vent modification done that should cure the issue.

Don't worry, I've already vacuumed out the dirt that fell into the cylinders when I pulled the head.









Here's a shot with the head gasket off:



And a shot of the head itself:

Tools from the work this weekend. This group was mostly for releasing the headers at the bottom where they join the cross over pipe. Embarrased to say I don't own a true stubby ratchet. I use the vintage Snap-On F-70 ratchet in the picture as a substitute, its reasonably short as you can see from the stubby wrench laying beside it - at least a couple of inches shorter than a standard 3/8 ratchet. The Vice Grips were for pulling the dowells from the head that locate the cam box.



Here's the big boys for the head bolts. A 3/4 breaker to get things going, a 3/4 ratchet for 3 passes of gradual loosening, and a 1/2 speeder once all the bolts are loose. The 3/4 breaker is so nice, instead of having to heave with a 2 foot 1/2 breaker, you can really apply gradual force. It was some crazy low price from Princess Auto when they did an introductory deal to launch their online shopping site, I think it was $23 with free Canada Post to my door, I couldn't pass up that deal. I'd say its typical Princess Auto tool quality, so not great, but I'm not an intense user of 3/4 drive so it should last me a lifetime.

Now for some bad news. My headers are done. The factory ones cracked 2 seasons ago, as most of them are now, you can't escape time. So, I cheaped out and bought a Chinese made OBX set for $300 that came with headers, downpipe and wastgate connector pipe. I only used the headers. Approximately 30 events later, and the street driving to-and-from, and this is the result, leak on one exit:



Major cracking along the line of welds on another exit:



I knew about the leak, I could here when it happened at the last Stratotech event. The cracked welds were news to me. My next set will be higher quality and hopefully will last longer.
