joshb530 Posted October 17, 2015 Author Report Share Posted October 17, 2015 Should I worry about #2 and #3? Quote Link to comment Share on other sites More sharing options...
psu_Crash Posted October 17, 2015 Report Share Posted October 17, 2015 Pretty solid numbers. I'd be a bit nervous about 2 and 3 since they like to fail between those cylinders. Although there probably isn't a lot to worry about at the moment. Just keep an eye on it. If the numbers continue to fall then I'd pull the head ASAP Quote Link to comment Share on other sites More sharing options...
scott87star Posted October 17, 2015 Report Share Posted October 17, 2015 2 and 3 are technically out of spec. I've seen numbers improve over time with some good synthetic oil and fuel detergent additives. My 140K mile car has 145, 145, 148, 145 compression numbers and they didn't start that uniform (at 100K when I got it). Quote Link to comment Share on other sites More sharing options...
joshb530 Posted October 18, 2015 Author Report Share Posted October 18, 2015 thanks, i will definitely keep an eye on it, i recently bought a parts car that has a low mi engine with a njv head, arp head studs and not sure what else until i pull it more apart.i may drop the head and studs with a good headgasket on mine if it gets any worse. i just did an oil change with a good synthetic 10-30w oil and am running a can of seafoam in the gas tank at the moment, ill check the compression again on my next oil change.need to get it through the good ole california smog check next week :ugh: Quote Link to comment Share on other sites More sharing options...
