OK, getting ready for some A/C install action and I went to swap out the heads from my Sanden 508. I believe I have amassed every part and item and I was very pumped. I also got ROLLGUYS kit, very nice !
Took a bit of mojo to get the old head off. This is a NOS Japan original, not a Chinese clone knock off. I got the pump, et cet from Secondaries over a month ago. Now, it's too hot for any more delays.
Then, per the spec's, 24-27 ft pounds, I went to the install. Guess what ? threads pulled right out ... poop. So, I am thinking my only hope is to helicoli the 5 bolts. Right now, I removed the thin metal star-like plate too. I am down to the pistons, so I am good for the clean up and re-install. Need to order the gaskets tonight.
So, any ideas or caution about helicoiling this? If it's a loser from the beginning, please let me know so I don't waste my evening or tomorrow in the early AM before Mr. Sun rises.
Thanks in advance.
