thanks Banan.


i thing in many sell video test, seller can put oil and make what compression he want ,but on this test seller stops starter of 2 and 3 cylinders earlier , because 1 and 4 have a little low compressions. look like healty 2 and 3 cylinders have 210-215 psi....

i don,t know how can compression test of engine 11.5:1 , give 14 bars?

find some info for redtop beams and is300 -195psi , and some info for 155psi for blacktop (11,5:1),,but not sure who correct one

(in idle and upon start , must vvti eliminate overlap,,,and some problem for compression test with jammed vvti wheels,)

my cold test is 170 175 175 140 hot test is 180 -180 -180 150 ,,,,,,4 cilinder is easy rider

I had a friend test compression on his engine. Around 165psi. But the thing you must look for is consistency between all the cylinders

I would also check your tappet clearance. The ti valves in the manuals can stretch so its worth checking this first if a cylinder is down on compression. No matter the value s u should get they should be within 10% of each other.

thanks....the head is 1500 km after service, but will check it winter when i open a block:(. ( the engine is little in firewall of my ae86,and cannot open valves cover now)

I bought a obd cable, and hope to find any irregularity in the engine because I feel it is not healthy and think that it have power loss.(maybe some like 20bhp)( new maf sensor,new o2 sensor.clear filters)
