After 20 Weeks, G8 is Back Up and Running

After 20 weeks, I finally got my baby back. Everything that could have gone wrong with the car did go wrong. But i'm really happy to get her back.

Story: Dec 1st 2012 i have two solenoids in the transmission fail, so i had to get it fix and the only way to get them fix is to replace the whole TCM. Which you cannot get here in the united states so i had to go to the dealer and get them to order the TCM from australia. The parts arrived 3-4 weeks later. Installed the part and had the dealer flash the tranny. I got the car back in mid Feb.

After driving the car for a few days I heard this loud ticking noise coming from the engine. So i decided to take the car to 510 Race engineering and in a matter of mins of taking the valve cover off. They found the problem. The upgraded trunion bearings failed and went through the whole engine.






So they had to tear the engine apart to find if there were any parts damaged or whatever. well during tear down they found out the person who did the build before, improperly installed the parts. Due to them choosing Comp cam lifters with ls7 push rods, it caused the trunions to fail as the comp lifters were too short. So basically I had to rebuilt the whole engine. Put a lot of new parts in the engine and now is better than ever.

Here is what all got replaced.
Cam
Crank, Cam, and Rod Bearings
Lifters
Rocker Arms
Trunions
Lifter trays
All gaskets
double roller Timing chain
valves
Oil pump
Spark Plugs
Piston Rings

Here is my baby alive at a cold start.

That's great but sucks about the motor. Is there any recourse from who built it before??

well no recourse due to the warranty was out already. shop only gave a year warranty and it was past. was also thinking if they messed it up before than why bring it back if they might just mess it up again. you know. so i just kept it at 510 racing engineering.

here is the new exhaust just installed yesterday.
