when working on the clutch saw an oil leak from the back of the cam tower. cleaned it up to determine how much.

after a few drives had the car back on the lift to replace the failed wideband O2 sensor. suspect it got contaminated by the raw gas when cranking to sort out the no spark. also changed the oil just in case gas got past the rings and into it.

well the leak was again evident. get back there to replace the gasket and found all the bolts loose. took a couple turns to tighten. will check back to see if I really need to change that gasket. not much room back there.

getting ready to replace the wrap on the hood and install these vents.

from reading the suggestion is to locate them near the front of the hood as that is where there is low pressure zone. any suggestions?

pulled the air cleaner, ducting, and the intake pipe to the TB.

was FINALLY able to find my small coolant leak. connection from the turbo WP to the turbo.

got a long screw driver in there and tightened. now after a test drive the loss rate is much reduced but still seeing some dropping.

so back to pulling out some of the intake and probably throttle body to get to it.

well..... found source of leak but not what I wanted to find 3 weeks before first DE.

head gasket. when pressurizing the coolant system with the intake off we could see the seeping from the intake side of the head. cleaned/dried and tested again. yep.



new fire ring head gasket kit on the way from LR.

will be pulling the head in the next day or two. kit on the way.

but on another topic, a friend had made a splitter for his 911 from a sheet of thin aluminum bonded to a plastic core. made a new one from CF so gave me his old one.

yep, enough to cut a splitter for the 951. will initially mount with only a couple inches of lip as I do not have any added spoiler in the back.

and the partnership of ANALOG-MOTORSPORTS and Anderson Auto Haus is gaining traction.

got the cam tower off. but fought a bolt on the header split connections for quite a while until the bolt finally broke.

I just had this all apart a month ago when replacing the clutch fork.

slipped a piece of cardboard in to catch the lifters.

checked all lifters and all in great shape. the PO told me this engine was rebuilt but did not have a build list.

end of the day and I considered removing the head bolts. but realized I forgot to hit the exposed nuts with penetrating oil. so gave them a squirt and will proceed today.

well another day of fighting rusted/frozen bolts.

I am replacing the head gasket due to an external coolant leak on the intake side of the head. all the head nuts came of easy but started fighting the two socket cap hex bolts at the front of the head.

they just would not turn at first, so hit them with penetrating oil and let sit for the night. next day after a fight one broke. started the fight on the second and had to come back the next morning to finish the fight. it also broke.

from talking to Mike Lindsey he told me this is not uncommon, especially when there has been coolant leak. those bolts can get very corroded.

so the head on both bolts are broken off, but I still could not pry the head loose. I tried with my pry bar, then resorted to trying to use washers and drive a chisel in between trying wedge it apart, still no good. finally got to working on it with my friend and we tried a 3' pry bar and a 3' piece of pipe. he had his full weight on it but looked like it was not budging.

well on close inspection I notice the exhaust side of the head had actually lifted slightly. when feeling on the exhaust side it was maybe a 1/4". I just could not believe what I was seeing.

after some thought, jammed washers and screw driver into the space for the prybar. then put the lower head bolt back on and started tightening with just a hand ratchet. before I felt much resistance the intake side popped loose.

it was end of the day and I had developed quite an appetite during this fight.

off the to farm to finish the spring refresh on the garden tractor and do the first mowing, about 3 acres.

well .....

the wedge and wiggle technique continued into a second day before the head come off.

was expecting another big battle but after putting the stud remove on both bolts I was able to just unscrew them by hand. it was all from corrosion between the bolts and the head.

so now getting optimistic I'll be able to make the DE I scheduled 4/27.

started by scraping the gasket stuff off the head. then went to the block and as I started looked into cyl #2. badly scoured ... badly.

so forget the DE and now starting to pull the motor. will strip down to the block and send to Lindsey Racing to over bore and drop in new, slightly bigger pistons.

sigh.....

Man, just get another block in the same tolerance group instead of spending all of that $$$

If yours is Group 1, there are many out there.
