Fresh Recruit
Hi everyone.iv followed this forum for quite a while but iv never set up and account.
Iv had my 1997 Glanza v for about 2years now
I sold it for a while but regretted it after about a day and had to buy it back.
Well a couple of months ago my car started spraying oil out the rocker cover breather which meant I had pressure building up inside the engine. I done a compression test and cylinder 1,3+4 had 170 and 2 had 90,so I took the head off and checked everything out,got the head skimmed and pressure tested and everything is fine. So then I put sum oil in the cylinders and it all leaked away within a couple of hours,so I'm hoping this just means my pistons rings are gone and the cylinders don't need rebored.now iv took the pistons out and have found piston 2 ring land has cracked and fell apart in my hands. This is my daily driver and don't really have the funds to go forged so I'm wanting to do it as cheap as I can but do I right cos I never plan on selling the car,I will end up forged at sumpoint,just not now.my problem is trying to find standard pistons,the only place I can find them is camskillz and they have 3 diffrent options 74.091mm 74.092mm + 74.093mm,I have no idea what ones to get? I don't have anything that could measure the old piston that precise.obviously I will be replacing all 4 pistons while there out. Does anyone know what piston size I should get and what could have caused the ring land to crack? I'm running 0.8bar on a standard ct9 and have air and fuel mods.iv read a lot of people saying that it could be caused by having the standard exhaust manifold still on. I did but a toyosports stainless steel one from eBay but that caused nothing but problems and I couldn't get it to sit right,everytime it was fitted it would leak,it was fine for the first couple of days but then the car would hardly boost atall andh sounded like a tractor so I just put the standard one back on. Thanks for any help,Steven.glasgow
