aluminum head retorque......

RE: aluminum head retorque......
Make sure you go back and retorque those aluminum heads. I paid the price for not doing that. I installed AFR 185s and did the normal torqueing. For the first 4 months it was ok. on the 5th Month I started noticing a loss of water in the Resevoir. I could not pinpoint what was happening to the water where it was going. Well, I started hearing a weird noise as if a rocker was loose. I went to check the oil level and BAM. I had fudge! Water mixing with oil. I was pissed. I thought I had a broken gasket because I had raced my friend and put octane booster. When I took it apart, and got to the heads for removal, I said to myself, "If some of the bolts loosen up to easily that is the problem" Guess what? On one head, 5 bolts were too easy to remove. Normally they take some torque to remove, but these five were being removed too easily.If you are thinking that I did not torque them correctly in the first place,let me tell you thatwas not the case. I retorqued themthree timesupon installation. I had two torque wrenches and they were both accurate. In my opinion what happened, isthat with the pressures of compression and water pressures, water slid in between the Head Gasket and wasgoing in threw one of the cylinders.
In saying all this, just go back and retorque heads after you run them for atleast 50 miles. (Thats my opinion only)
In a way what happened to me was ok, because of all that, I instead of putting it all together the same as I had it (Flat Top Pistons) I went ahead and got Dished Pistons for the SuperCharge setup.
Goodluck!
