Blown Motor, Engine Rebuild/Replacement.

COSMO · 02-10-2014, 11:33 AM

I managed to get a little more prep ready for the engine to be pulled out tomorrow. Here are a few pics and yes that is metal chunks sitting on top of the valves..

What part broke, piston or rod?

COSMO · 02-10-2014, 01:46 PM

The motor will be out tomorrow and I'll will know for sure but I'm guessing a rod. The valves are intact...

Looks like part of a piston land sitting behind the right valve.

Thats what I was thinking. You would think if it was a piece of rod, it would have to get past the piston. If it did that its a lot worse than just the rod lol. Im thinking broken ring lands.

If it was a rod. Chances are, it would be out of the side of the block. Be real easy to see then.

Years ago. I worked on a ferd 300ci straight 6. The guy said it was down on power, but had no strange noises in it. When I removed the head. I had two pistons at top dead center.

Turned the crank over by hand, and watched all of the pistons move, but #6. Removed the oil pan and everything looked good.

Unbolted the rod cap from #6 and pushed the piston and rod up. What happen was the piston broke in two at the oil ring land.

No damage to the cylinder wall. Got another piston and new rings and install it.

Hopefully your motor could be like this.

Im sure it looks worse than it actually is, but that process looks like a nightmare lol.

I'm curious to see if I find any Cracks on the exhaust manifolds... Stay Tuned!!

How long have you had your FI setup? Those valves are clean. I need to get catch cans for mine since I have this paranoia with oil blow by. I need to pull stuff apart to clean it once the weather gets warmer.

COSMO · 02-10-2014, 02:51 PM

I have about 3-4k on the TT Kit..
