yep the pin is in the rings, and he's going to put new rings how wide can he put the oil gap?88Stangboy said:Does the stroker kit push the wrist pin up into the rings? What did he set his ring gap at, or what was it set at, do you know? How many miles on the engine?
I read a article in muscle mustang and fast ford mag that said by 10000 miles 347 will usally start using oil. they say nature of the beast. they article was trying to show that a 331 stroker kit was a much better kit for street applications. in this case however i would agree that the oil consumption is excessive. I would inspect my intake. remove the tb and see how much oil is actually being diverted to the intake via the egr. You didn't mention if he as any oil leaks.304billet said:A properly built 347 will use no oil just like a 306/331.
Did the engine have blowby which would push the dipstick out of its holder? If the dipstick was not pushed out, then the intake may be sucking oil and vaporizing it. another potential problem could be the PCV valve.
He should have done a leakdown test to determine how much compression he is losing . A good motor has between 2%-10% leakdown, anymore than 10% time for a refresh.
Also a leakdown test will not determine if the piston scraper rings are stuck or frozen. The piston scraper ring scrapes the oil off the cylinder wall and if they r not functioning properly u will burn oil.
another oil burning problem is bad valve guides or valve seals. I have heard that using teflon valve seals on a street motor causes excessive oil consumption.

lol that could be.Nick302 said:Not this again.
Clue #1 MM&FF
Lemme guess, it was the DSS article. My guess is they weren't selling enough 331's
Nick302 said:That's a whole 'nother discussion. Personally I'd rather stick with a 347. Stock hood, stock brackets etc, no need for 2k dollar heads and all that. People will only know you have a 347 if you tell them.
