Eagle Posted September 27, 2014 Share Posted September 27, 2014 Will zmax or anything help? To help what? You don't know what's wrong, so how can you figure out what may help? A quart of oil in 500 miles is a symptom of a MAJOR problem. I think either your rings aren't seated, or the cylinder walls are scored. You can't figure out which without removing the head and inspecting the cylinder walls. Link to comment Share on other sites More sharing options...
thejim42 Posted October 20, 2014 Author Share Posted October 20, 2014 I'm pretty sure my issue is valves. I just took the truck on a 1500 miles round trip at 75mph and didn't burn any oil. But at start up and before the engine gets up to temp I get a lot of smoke at idle, and when I take off from a stop I get a big puff and thats it. Is it fairly safe to assume that i have a valve issue? Link to comment Share on other sites More sharing options...

Is it fairly safe to assume that i have a valve issue? Dunno, but valve seals (which aren't really seals, but "deflectors") are cheap and a lot easier to install than doing a tear-down. Give it a try. Link to comment Share on other sites More sharing options...
thejim42 Posted October 20, 2014 Author Share Posted October 20, 2014 Don't I have to pull off the head to do that? Link to comment Share on other sites More sharing options...
shelbyluvv Posted October 20, 2014 Share Posted October 20, 2014 No you don't. You can get a air chuck that threads into the spark plug hole. Presurize the cylinder with both valves closed and remove the spring locks and springs then replace the guide seals. A old hot rodder trick is to get the cylinder at the bottom of the compression stroke. Remove the spark plug, feed some heavy string down into the plug hole. Then rotate the engine back up to TDC. The string will hold the valves in place so you can remove the keepers and springs. Then replace the guides. I have used the second option a few times and it is much cheaper and easier than the air method. Link to comment Share on other sites More sharing options...
Eagle Posted October 21, 2014 Share Posted October 21, 2014 I've always used air. Link to comment Share on other sites More sharing options...
