Asthmatic B18ft coughs up a piston!!

Did wonder why the oil tried to exist the engine though the breather on boost!!

Stripped down the track clio today to find this:

Got a nice go faster stripe down cylinder No1.

Broken piston was in No2. No3 piston has some major det marks on the side of it. ( Wasn't Me - previous owner causing this with stupid boost, i never checked bottom end until now )

I did a compression test on the engine before i stripped it down, all cylinders read about 140 psi. I just thought the rings was lunched :crap:

Now where do i go from here?? I have a spare engine that i can rob a piston or 2 out of.

I was planning to glaze bust the cylinders, re ring and rebuild it.

Thats a ****ter matey maybe a new piston and a good honing may sort it:cooter:
speak with marky mark matey. He is building up a lot of b18ft stock at the mo may be able to help;)

Yea already got Marky Mark on the case with the rings as i suspected the engine had issues :D

Well she is all back together now, Done a track day in her and it did'nt spit out one drop of oil :D Win.

Took her for an MOT today and she Passed :yeah:

Road Legal track slag :cool:

Did you just hone the cylinder and bang in another piston with new rings?
