Head Gasket / Compression??

[wayfarerstranger]

HELLO FOLKS !!!!!!!!!! can anyone shed some light on this ? here is a little history , i have this 53 model truck engine in my 52 DODGE WAYFARER coupe .. was running just fine a few weeks ago car has not been drivin`car has just been sittin` since last year , bought a new battery for it so i could do some work on it , like to have never got it cranked up ,after messing with everything it finally fired up but shook like hell & ran very badly, swapped out some different plugs it fired right up & ran a lot smoother, HERE IS WHERE THE PROBLEMS STARTS it runs but when i try to rev up the motor it doesn`t really do anything like the power is gone ,also noticed the car smoking a lot "white smoke" out the tail pipe never smoked before also smoking around the exhaust manifold i looked and you can see liquid bubbling around the manifold just in front of the carb.... i`m thinking coolant leak blown head gasket, but how does a car blow a head gasket just sittin` still and not being drivin`? anyway so i pull all the plugs & check the compression 90 110 110 110 110 90 , ok that`s got me puzzled ? so can a car have a blown head gasket and leak coolant & still have super good compression ?? thanx CHANCE

When you pulled out the plugs did you notice if one was wet?

[wayfarerstranger]

I`LL go recheck the plugs... but motor is smoking like crazy down below where the exhaust pipe bends and rolling out of the oil filler tube also ,, i`m thinking the damn exhaust might be clogged up some how ?

[wayfarerstranger]

i repulled the plugs none are wet all are cover in black soot ... on the first set i pulled one plug may have been wet ? maybe a little ..

Mice have been known to build nests in mufflers or exhaust pipes in cars that are stored for extended periods. I have an engine that had a hugh mouse or rats nest in the oil pan.

I'd bet that when he changed the plugs he accidently switched a couple of plug wires. Been there, done that ......

Basic rule of thumb, black smoke = oil, white smoke = coolant, blue smoke = gas.

[wayfarerstranger]

the wires are correct ,, i disconnected the muffler didn`t help ... engine still won`t excelerate very much , just seems to have no power ,, the white smokes isn`t coming out the tail pipe,,,, it`s just pouring out of the oil filler tube and the vapor tube coming out the side of the engine .. which is odd never seen this one before ?? so to original question can a motor have a blown head gasket and still have great compression in all cylinders ?? and if anyone has any ideas what to check here ?? thanx CHANCE

what do the vacuum readings look like could it be something blocking or leaking at the intake manifold,exhaust manifold

Are you losing water or oil

[wayfarerstranger]

can`t really tell if i`m losing and fluids but it seems something is blocked but what ? i`ll have to get a vacuum reading, it just happened , one day running fine the next like something just stopped it up , and forcing white exhaust smoke out of the oil filler tube & the vapor tube ...

What does the stuff on the dip stick look like??? Oil and antifreeze or water make a light brown milk shake looking stuff. Also if you have just been making short runs and condensation builds up, and you have a bit of ring blow by, the vapros will come out both tubes. Check the oil and see what it looks like, smells like.

[wayfarerstranger]

oil seems fine , this ain`t regular blow by .. white smoke is pouring out it`s like something is clogged the exhaust and it is pushing it out other places , we are talking a lot of smoke , and its white like the coolant is leaking on the inside some how .. i guess i`ll have to pull the head if i get another run of good weather ,,

I would check out the road draft tube breather set up too. If that is plugged it could cause problems. Good luck to you.

Check the oil filler cap also to see if it may be plugged.

Chance;

If you close off the oil fill tube with the palm of your hand can you feel any pulsations when the engine is running? If you do feel pulsations you have bad rings or a broken piston or both.

If you remove the radiator cap while the engine is running do you see any bubbles? If you do you have a leaking head gasket.

Did you do the compression check before or after the smoke started?

[wayfarerstranger]

WELL i`ve had oil filler caps clogg before but , i removed the cap this isn`t the problem , i`ll check the down draft maybe a rat built a nest as i found a dead one under my car a few months back ? seem logical as it was fine then it wasn`t ? the bad ring & piston was my first thought just was hoping i was wrong , but i`ll go check it with the Don trick " hand on the filler tube " & i `ll check for bubbles in the radiater too . i`ve only had a little time to spend on it " as i`m been busy getting CHRIS`S D-24 going ...so i haven`t checked everything . At this point i would just like to pin point the problem .. will update later if i find anything new ,, again thanx .

[wayfarerstranger]

OH YEA DON , the test was done after THE SMOKE STARTED ....

[wayfarerstranger]

i`ve checked everything and can`t seem to get any clues .. i checked the down draft pipe it is fine , i put my hand over the oil filler tube can`t feel any pulsations , there aren`t bubbles in the radiator ,the oil isn`t milkly & looks ok , the plug wires are on correctly , just lots of white smoke pouring out of the the oil filler tube but not the exhaust pipe ..and it smokes pretty good after i turn the motor off just like steam rising . it will crank right up now time you turn the key and it has 40lbs of oil pressure & 95 to 110 compression in each cylinder . no knocking or rattling , still the smoke and hardly any acceleration ,,, something has gone wrong on the inside . just can`t imagine what since the motor ain`t giving me any clues ?? thanx for the input , i guess i just have another problem to deal with ..

You repeat that white smoke is coming out of the oil filler cap, but I have not seen your comments on how much is coming out the draft tube. You may need to pull the draft tube to make sure there isn't any blockage at the block.

[greg g]

Also when is the smoke more apparent, when the engine is running or after shut down?

[Bodacious]

Basic rule of thumb, black smoke = oil, white smoke = coolant, blue smoke = gas.

You got that a little mixed up, didn't you? Black smoke is from unburned gas and blue smoke is oil burning.

[wayfarerstranger]

THE draft tube was pulled and it is not the problem , there is smoke coming from the D.D. TUBE it is steady but not as bad as the oil filler tube ... the smoke is white .. time the engine starts up the white smoke starts pouring out,it is a steady thick flow when i shut it down the white smoke continues, a little less thick but doesn`t stop .. like i said before , like steam,, like if you are boiling water on the stove and steam starts coming from the pot then when you remove the pot it`s still smoking .. and if there is any smoke coming from the tail pipe it is very little if any ? which is odd.. like the smoke is being redirected .. if the head & manifolds are removed i may see the problem because we can`t seem to diagnosis the cause .

Starting to sound like a cracked block or bad rings.
