im burning oil bad and suspected it was busted rings... but when i took out cylinder 2 some oil came out also... so it seems im burning oil from the the valves...

this means i dont need to buy a new engine but need a head rebuild:) good news for me!

or are you hear for our rolfcopters?

im so happy, cuz i was about to buy a new KA for $200... now i could use dat money for a in the engine bay rebuild...

im gunna get a timimg chain from FRsport, a new knock sensor, and get my head machined along w/ valves... then ill need to find where my leak is coming from, reseal the oil pan w/ gasket, and thr in some nismo motor mounts:)

look for a build coming soon!!!

what are you going to sand blast and why?

carbon build up sticks to the seat so that it doesnt sit evenly and im my case its because my valves seals are old and cracked so that i leak and when the oil burns it builds up on the valve...

sand blasting is air and trillions of fine crystals be squirted at very high psi braking loose the carbon and making the valve like new... this way i dont need to buy new ones and save $300

you guys make fun of me make fun of me like youve never heard of sand blasting before...

Oil is sliding through where the long rod is on those valves. Called a valve seal. Take the head off and replace em. I did a writeup that didn't get put into the articles section that you may search for.

Sandblasting them will help get the carbon off, but may just fuk up their surface so you'll have to re-seat them anyway. Just use goof off or carb cleaner to clean the valves duhhh

edit for claro clarity:
Your compression is wonderful, which means even IF your valves have soooo much carbon on them (LOL) they're seating and sealing perfectly fine. You're correct the problem is oil coming thru the valves, but it has nothing to do w/ the valve seal seeing as the valves OPEN and thus the oil slides down the shaft and valve and enters. Sry we were all nubs once. I apologize but you acted like you knew exactly what was wrong and you weren't totally right so...

Also op, this is the 2nd time I've told you. your sig is filled with annoying nub grammar. the word site is a website, the word sight is the act of seeing.

and id rather SEAFOAM

Seafoam is great, but because you'll have the valves out your money'd be better spent on carb cleaner because it comes in a spray can. Steel wool it after soaking and you're good to go.
Seafoam is better for use if you're not taking the head off because it uses combustion to extract carbon, but it still will do a bangup job without ignition.

Sandblasting valves....... thats as bad as flushing the dirty oil out with water. Or porting and polishing your head with sand via engine vacuum

He could mean this website.... you know, a play on words.
