^^^oh yeah forgot about air pressure. and yeah i just saw USA under your avatar and didn't notice Colorado till just now lol so yeah now i gets.
as for the leakdown/compression test. better to get it done sooner than later before it gets worse.. dont take it as bad news. for all you know a slightly lower compression in 1 cyl could just be a stuck valve it carbon buildup etc...
Also if 1 (or 2, or 3, or if all 4 cylinders are gone you're not going anywhere.) cyl is dead, the others try to make up for it. Makes it ware harder on the motor too. Fix things before they break, if you can't, fix them as fast as you can. It will cost you more in the long run if you leave something damaged or broken for when you "have" the time and money. If you fix it later you may end up buying/paying more to fix the problem... brakes are that way 99% of the time when people don't fix them when that annoying squeal starts. Also that squeal make you look poor and like you have a P.O.S. car!!
i got a b16a2 with about 190k on the clock
and my compression test showed
155, 150, 160, 160
isnt vtec engines surpost to have high compression
can anyone help me out, would it be time for a rebuild or recondition?
and i wanna run boost later on so would it be worth saving up for a rebuild setup that can run boost safely, or would it be better to rebuild back to stock and then get a bolt on kit running low boost??
thanks for any help
whereabouts you located, if someone here with an FSM could check their B16 book for tolerances then you should be sweet... at this stage i'm not sure if those figures are OK....Quote:

lol isn't sea level the same everywhere?Quote:

^^^bah thanks for the pickup... i meant altitude in general as discussed above by Slow96GSR and myself :p
im from melbourne, im not sure but does the altitude here have anything to do with it?
The leak down test will give you a much more accurate view of engine condition..there are some variables in compression testing such as battery voltage that can affect readings..is good for preliminary testing but not the test to really establish engine condition
thanks for that, i'll get the mechanic to do a leak-down test, when i get my major service doneQuote:
