burning a quart of oil a day, HELP!

[jetbuilder]

I just installed a freshly built high compression KAde bottom end. fresh seals, metal head gasket, rings, stem seals, and so on.....It's burning oil so bad that I can't drive 40 miles without having to add a quart of oil. I did a compression test and It's pumping out 250 psi from each cylinder. I thought it might be some how sucking oil out of the PCV system directly into the intake so I plugged the line ans there was no change. I'm gonna pull the intake manifold to see if it is leaking from inside the manifold or on the head. If the manifold is free of oil, I'm gonna pull the head and see if I can find anything wrong with it.

This is really pissing me off since I've been building this engine for 4 months only to have it burn as much oil as gas!

HELP!

you have new components on the bottom end?..ie pistons and RINGS?..couse sumpin aint rite there man..could be valve seals could be a bad gap in rings and or pistons are wrong sizes...or your head gasket was not seated correctly..need more info on this.

Brand new pistons(.30) and rings, block was bored .30 over. the shop measured the new pistons and bored the block accordingly. new bearings, full gasket kit including stem seals.

i would greatly appreciate it if you find out what is wrong with your motor . i had the same muffukin problem i had a dualcam that had little to no compression in cyl4 so i do a rebuild new timing chain and everything assoisiated with it gaskets, rings, bearings etc... and i put it all back together and it smoked like crazy take the plugs out and they are all covered in oil look down in chambers puddled in oil so i plug the pcv nothing, so i make a oil/air seperator and still nothing so i removed the intake thinking the the pcv had sucked all the oil inthere and cleaned it up,no effin luck so i gave up on that motor and purchase another motor and put it in now its overheating this convertible that i have has been nothing but a money pit

so i beg you please find out your problem i am tired of diagnosing this one motor and oh yeah the comp numbers were crazy because of the oil across the board they were 238-240-226-242

there is only 3 ways you could be burning oil that i can think of..

#1) head gasket........sometimes people forget to torque and then loosen again and re-torque there head gaskets..causing a falure..allso..you may be using the wrong style gasket for your aplication and not even know it..as there is no magic tuner book in the states like there is in japan with option mags..ect...we only get crappy articles that advertizing pushes on us...#2) pistons/rings....after a rebuild..you do need to go throu a break in period...but i never ever herd of such an oil loss with standard break in...one way this can happen thou is with the wrong size pistons or with rings that were gapped improperly..but even then..the gap would have to be large..#3) last but not least would be those pesky valve seals...these little bastages are a real pain...and if there leaking..you bet you would have fouwl'd up plugs ect....

now that we can narrow it down..its time to be sherlock and find the culprit!....#1. rule of tuning....never trust a build shop!..verify every thing your self...

********************recomendations*****************#1) head gasket...i dont know about others..but i only use full Copper head gaskets..they run $85.bucks ...and need some machine work for your head and block ( meatal O ring and reciever grooves) $200.bucks...so basicly 285.ish bucks for a head gasket that can withstand 7000hp...thats rite 7000hp..ps..requiers a spray on sealnt..hard to explain..but as you can see..next to impossible to blow...great for turbo cars.

#2)..i would recomend that you pull the valve cover off and cams..take (1) buckt and spring set out and verify the valve seals were changed..on each piston on each side..so (4) total...and if this is still not the culprit...the its off to check #3

#3) pull the head off of your block, remove the rod bolts and push the pistons out the top of the block from the bottom side...and meashure bore in (3) different places top/middle/bottom of each cilinder no less than 6 meashurments per cil....then meashure your piston's acording to the piston makers diagram..you will allso need to know ring gaps and the maximum allowd tolorance for piston slop...

this may all seam a hardcore task..but in reality..once you know how to do the above...you will laugh at all the times you had someone else do the work for you...hope this helps in some way..and i wish you luck sire.

was the head gasket made for that big of a bore and does the head match? if not it could be getting some leakage from that.

But was the head gasket for a .30 over block? Also are your rings in the right direction?Did you rebuild it or the shop?Any irregular noises? How high is the compression?What brand pistons, rings, and gaskets? For the head gasket, did you get the block decked and head milled?

If the shop did all the work, then call them and tell em.

spanks got a huge point man..if you had all that done at a shop..and your burning that much oil..id take it back to those poons and have them fix the issue...if not..take em to court and get a refund..in the meantime..you might think of looking for a better shop..couse it iant workin out well at that one bro...if ya know what im sayin...those are about the only options you have at this time....gooood luck.

no need for a metal headgasket.... felpro will get the job done just fine..
