Re: Valvetrain Metal Expansion Compensation?

I did not intend on making this thread because setting valve lash is difficult. It actually is quite simple. My goal was to find out if anyone has come across a problem setting their clearances tighter or looser than the nominal clearance with whatever set up they may have. I spoke with my machine s...

Re: Valvetrain Metal Expansion Compensation?

Nope. The article didn't mention anything about valve to guide clearance. I use feeler gauges that i measure with my micrometer, to be as accurate as possible. Sometimes a combination of a few gauges and a little math can allow me to check clearances in increments of about 0.005mm, but sure is a pai...

Re: 4AG Turbo oil loss ?

Yeah I know.. That's a lot of oil. Shaft play seemed normal(even @ idle), but I'll take my intake off and use a dial indicator to get precise measurements.. So jondee86, will it be more beneficial to Vent the can to atmosphere or reroute the hose to intake(I thought the benefits were negligible...)?

Re: 4AG Turbo oil loss ?

There were a lot of short trips in cold weather, which explains the condensation.
Over the course of the 3000 miles going coast to coast, I spent about damn near a 5 gallon jug of oil.

What is the other way you suspect I am losing oil?

Re: 4AG Turbo oil loss ?

I should have taken pictures when I drained my catch can the last 2 times... There wasn't a large amount of oil in the can. A little bit oil and water mixed sludge at the bottom, but was only 1/5 of what was in the can- the rest being water from condensation. The amount being less than a 1/3 of the ...

Re: 4AG Turbo oil loss ?

Re: 4AG Turbo oil loss ?

I think I like Jondee86's advice with baffled breathers. I don't plan on reusing anything caught in the catch can. I'm planning on running a baffled breather on each valve cover to a catch can with a breather on top of the can. Do I need to plumb the outlet of a can to the intake, or would that caus...

Thanks for checking the dipstick man. I indeed have a small port block. I always filled the dump to the full line on the dipstick. Overfilling may be in question when I filled it to about near the top of the "F" when I noticed I started losing a lot on the cross country road trip, but do y...

Re: 4AG Turbo oil loss ?

I saw that picture after extensive hours of searching prior to starting this thread, but questioned whether or not it is the correct dipstick.

If I'm not mistaken, it looks like the thicker 4ac one. I have a yellow handled one that's not as thick..

Can anyone verify that dipstick?
