- Mon Apr 11, 2011 5:22 pm #249718 ok so i went out and got a compression tester and checked the compression on all cylinders...

1...110
2...105
3...105
4...100


so i know thats like really low, but what would cause the low compression in all cylinders?

- Mon Apr 11, 2011 8:40 pm #249755 Have you checked your timing? Sorry if you have and i forgot.

Put a little bit of oil in each cylinder and repeat the compression test. If your compression raises its your rings. Otherwise it would be head gasket or some other cause like bad valves.


(perhaps, but i cannot say for certain, it could also be that your mechanical timing is off).



But it looks like your finally getting somewhere on getting this thing running which is great. If your compression does not significantly rise then def check your timing (if you havent). If your timing is ok then its time to pull the head.

- Mon Apr 11, 2011 9:32 pm #249773 yes it was smoking but it was cause of the unburnt fuel.

rechecked compression w/ oil

1...140
2...150
3...155
4...155

so it went up but could all my rings be bad?

ok so in checking my timing i understand the concept but how do i know when #1 is top dead center with out pulling my head?

there's a mark on the lower timing belt cover.
rotate the crankshaft CCW until it lines that up with the white mark on the crank pulley

ok simple enough, so i went to my car and...no white mark on my crankshaft pulley. just a hole and 4 dash marks. then where is the mark on the plastic? is it a line?

Unfortunately if it was your timing i doubt putting oil in would have made any difference at all.

However depending on the amount of oil you put in its possible that you got false readings. I think the rule of thumb is about one tablespoon in each cylinder.

The line might not still be white but it should still be there (the first dash that is spaced a little before the other 4). Just might have to really clean the pully good before its visable. The mark on the cover is a petruding peice of plastic i think on your engine it'd be around 12 o'clock.

all 4 lines are evenly spaced like a clock 12,3,6,9 but one has a hole next to it

- Tue Apr 12, 2011 12:48 am #249821 What he meant on the crank pulley you should see something to this. obviously this here isnt round but here is the concept..



I I I I I


^

THIS LINE RIGHT THERE SHOULD BE TOP DEAD CENTER (WHEN PISTON #1 HAS REACHED THE TOP). OR IF YOU HAVEE LIKE A 10IN 3/8" EXTENTION OR REALLY LONG SCREW DRIVER. PUT IT IN THE SPARK PLUG HOLE #1 NEXT TOT HE TIMING BELT. TURN THE CRANK TOWARDS THE FRONT BUMPER(COUNTER CLOCK WISE) AND ONE THE EXTENSION OR THE SCREW DRIVER U HAVE IN THERE REACHES THE TOP OR STICKS OUT THE MOST IT CAN U HAVE REACHED tdc AND THEN GO LOOK AT THE CRANK SEE IF IT'S LINED UP THE THE LIL ARROW PIECE UP POPED UP PLASTIC ON THE LOVER TIMING COVER. hOPE THE HELPED..

Heres a pic.

- Tue Apr 12, 2011 1:14 am #249834 sorry dude. If you were closer id come over and help you do it.
Assuming your compression guage is functioning and was tight when you checked the first time though the numbers do not lie. I hope the rebuild goes well for you.

Definitely pop that head off and have a look. Its possible that someone put the head on wrong and the cylinders are all leaking into each other or something.

it is a brand new compression tester, so it better not be bad...lol.

why dont you take some vacation, its been beautiful weather up here in ND...lol!

but i'll keep this updated as i keep moving or just start a new engine rebuild thread or just update my build thread...one of the three

Sorry missed this comment. It depends, if your looking for a stock rebuild kit just check prices between oreillys advanced and autozone. If you want something aftermarket i can only recoment shopping around.


lol, i wish i could take some time off. Id love to go on a vacation. Yes, def keep something updated.
