Oil pools on all piston tops
So I just finished rebuilding my ka24det, due to detonation damage in all cylinders. I start up the engine for the first time and it's running very strange exhaust manifold glowing red and backfires ect. Checked timing on distributor and it was a tooth off. After it was running great! Except now I'm having a problem with oil smoke (blue) after engine is warm. I have one of those bore scopes cameras so I decided to check out the piston tops. I found that all of them have small pools of what appears to be oil settling on the exhaust side. The spark plugs look good from what I can tell. I changed the valve seals and some of them were bad / floating on the valve stem. So I figured great this will be an easy fix. Nope still getting smoke. All the work done on the rebuild.
-head decked -valve job, seats, guides -valve lash ( cut tip of valve to correct spec) -tomie 1.2mm head gasket -arp studs -upgraded to oil relocation and cooler -retune on ecu -blow through maf -isr t25 / t28 turbo ( sitting for about a year new bnib) It's seems to blow blue smoke if I give it quick heavy throttle and if I let the engine idle for awhile it will blow out a decent size cloud. The bottom end was also built about a year ago Cp pistons eagle rods clevite bearings Also the compression test results are very high 205 cold in all cylinders and 215 warm. Before the rebuild it was 145/ 155 avg. But due to the oil in the cylinders I feel that it's giving inaccurate readings. Next step is leak down. Any suggestions or help would be greatly appreciated Thanks Again |
