okay well two days again i suddenly lost power in my d16z6. I go for another .25 mile and the car dies. now the car recently sat for 3 weeks before and was difficult to start a friend of mine said the compression was low in one cylinder. i do see fresh oil on the tranny also when i started the car the day after i it started from sitting 3 weeks i did see little blue smoke any idea whats going on?

if you suspect a blown head gasket then disable the fuel or ignition systems so that the car will crank but not start. remove the radiator cap and crank the car, if the head gasket is blown then you should see the coolant bubbling out of the radiator. That would explain the lost compression in a cylinder.

i know this might be a silly question too some but can the distributor also cause low compression?

punkinbeck

nope, has nothing to do with the transmission fluid or the distributor

Any cel codes?
Has the coolant level dropped? any problems with overheating? Is there any coolant on the oil on the dipstick?

Shaggy143Music

you need to check your coolant and oil. do the test i explained above. it should give you a good idea about what it is

jdmkidd23

okay ill try that thanks too eveyone that helped!!

jdmkidd23

i did the test to bubbling level was fine.! now could it be a bent valve or bad ring!! cause like i said in the number 1 cylinder compression is low the car before it died sounded like it was puuting along...oil is clean on dipstick!

You can do a cylinder leak down test on that cylinder. if you here air escaping through the exhaust of intake then it is prolly a bent valve or a valve not seating right.

So the car dont start right, It just cranks? Check spark and fuel. Usually with a loss of compression on one cylinder, the car still starts up but runs like crap.

I forgot to say that if a car blows blue smoke on start up after it's been sitting for awhile, it's usually bad valve seals.

yea im gonna check spark but car doesnt start like i said i was riding down the road and it just loss power and shut off! so it cranks but doesnt start!

In Over Thirty years of Honda repair experience I have never seen low compression in one cylinder cause a stalling problem,Only a misfire. A blown headgasket can cause stalling only if the engine is overheating.Next time it stalls check your fuel pressure and spark. Check your valve adjustment. To tight can cause low compression. Do the leakdown test as suggested by others. This will determine the problem. Good luck
