I bent my valves recently and had new aftermarket valves installed. This was about 500-750 miles ago and since then I have had to put in about 4qts of oil. I was thinking it was the valve seals, but not sure if its the rings. The shop (DRT in Queens, NY) who installed the valves says its the rings, and that he did a good job with the valves. So I took it to another shop and we did a compression and leak down test, and he thinks the first shop used the original seals with the aftermarket valves and they are leaking. He thinks the results of my compression test were OK, and that its normal if a cyclinder is off by a little bit, as longs as its not more than 10%.
Cyl #1 = 210
Cyl #2 = 230
Cyl #3 = 230
Cyl #4 = 230

Is this normal...advice and opinions needed on rings or seals...are these #'s normal.


I have this thread in the ITR forum as well.

Was there oil on your spark plugs? I'm betting it's the rings if there was.

 

Yes there was some oil on the plugs...but they were not drenched

 

4 quarts in 500-750 miles?!! That's about a noah's ark situation!

I use a quart a tank of gas <200 miles> in my mustang with 8 cylinders, and it blows smoke everywhere pretty regularly, and my #8 plug is DRENCHED when I changed em recently.

Is there a badass leak somewhere?

 

No leaks...justs smokes when I really get on it. So it might just be burning oil when I am above 7400 RPM's...that is where my VTEC is set at.

 

Sounds like valve seals to me. Many Mitsubishi products, especially those made in partnership with Chrysler, had this problem. My dad used to have a Plymouth Voyager that drank oil and blew tons 'o smoke. He replaced the valve seals and the problem went away.

 

if you burn oil under acceleration it is most likely the rings, if your burning oil during deceleration than its the valve seals on the exhaust side you could have good compression #'s and still be burning oil, how many miles does the block have?

 

I noticed if I let my car idle for while then rev the engine it puts out a good bit of blueish smoke, but goes away after constant revving. My compression numbers are good. My engine has 1000 miles since JG rebuilt it(Head and Block). What could be the cause of this?
