It was a good times but now its over.
It was a good times but now its over.
Well its been 6 years since i bought the motor and tuesday night i took it out to our bimonthly drift practices and blew her up. I was in the middle of a really crap run running about 2nd gear at 7K and i hear a loud pop thought it was a tire so i kept going stopped on a bank turn asked a friend in the stands said my tires looked fine so i went back at it. after about a min or two of 7K running as i was leaving the track the car began missing and died. i coasted off the track pop started her and it limped to the pits. i was blowing smoke and oil all over comming from the dipstick tube and breather hoses. pulled the plugs and they are still good, crossing my fingers that i merely took out a felpro HG. we will see later tonight, ill post pictures soon.

keep us posted.
no harm in showing us some carnage pics too.
Ps 6 years is damn good for a motor nearly old enough to drink now.

Re: (dash)
jon, i have a cometic gasket, it was used once, i dont like cometic, but its yours if you want.
Kemp i may take you up on that! i ordered a new felpro friday while picking up supplies for a SR build we are doing.
The motor had CP pistons and rings. HKS cams tomei valve springs and retainers. Evo8 turbo and megaquirt i was running about 18psi at the track. we added some timing over all to my map blindly and un tested at that. not smart to do, but i wanted to get some low end torque added. The car was running great. its sluggish off boost and needed a good refine on its tune, but it was driftable in 3rd gear as long as you held the speed up.
I took it apart hastily last night as i had other plans that were more important. but i got the head off and i should have done a compression test first as my HG was in tact. this leads me to believe its somthing else. possibly i warped the head, but it did not show any signs of flame travel on the HG which i would expect to see if combustion made it into the oil system an pressurized the crank case. Possibly i broke a ring or ringlands or multiple. but the pistons and head show no signs of detonation or melting what so ever, they have decent carbon build up but cleaned up around the edges easily. im leaning towards its that or i lifted the head. two of my head bolts were not as tight as the rest when we took it apart.
tomorrow im pulling the engine the rest of the way out of the car and pulling the oil pan and the rods to check the ring lands. I may build some sort of pressure checker to try to get around that as its hot as hell here and im lazy when its my car. i would rather spend two hours building the device then having to pull the motor apart. The head will be going to the machine shop monday to get checked. I have a spare if i warped it badly.
