I think the blow by on my CSX is pretty bad. Im getting oil coming out of the breather catch can filter......however, I open the drain and there isnt any collecting at the bottom, so it might just be the way the thing is set up. Is there a good way to test how much blow by the engine is producing and determine if its excessive? Car runs strong, it just seems to be dumping more oil than usual out the breather.
Also, what are thoughts on 20W50 Mobil 1 oil to minimize the amount of blow by?
Leakdown test.
I guess you could rig up a gauge to measure crankcase pressure, a leakdown test will bo much more accurate. 2% leakge is excellent, 10% not so good =(

Oh yea. DUH! Ill get on that next week.Originally Posted by guyd_15
even a compression test will show sometimes .
I don't even bother doing compression tests now- I had one compression test come up fine and then when leakdown tested showed one hole down 50%!!
Epic Fail
Working on clearing the decks.
already have the spark plugs out nso it takes two seconds. mine did work it was 105 across the board lol not to bad for 180 thousand i guess
105 is really bottom of the barrel.......I guess for 180k, its not horrible, but they should be up over 115-120 at the lower end of "good". I new engine will be 135+ with a swirl head.
Im gonna do the leak down tomorrow. Hopefully, its good. I have a feeling #1 is low b/c the compression is at 114 while the rest of the cylinders are at 125. Unless the leakdown is horrible, im just gonna run it for a while. I just re-ringed the thing and for whatever reason that #1 isnt seating very well.
Make sure its warm also.
You can rig a hose outside off the PCV system so you can see how much smoke is coming out,

well a compression test like that is on the borderline of needing to be tore down since a difference of twenty between cylinders is a big deal and you are very close.
Are those numbers for compression hot or cold? Cold or having sat for a few hours, mine is 120-125 on the compression test. I'm going to look into getting a leak down tester though.

Yes, its probably inevitable that it will have to come apart again, but im hoping it makes it through SDAC OK and I can drive it for the summer. Then, tear the head off and try again on that cylinder. Im tired of tearing the damn thing apart, so if its blowing oil, its blowing oil.
Well, looks like i may be giving that cylinder another re-ring before SDAC. Crap. Compression is down to 105 and there is a considerable more leakage than the other 3.
sure its not a head gasketWell, looks like i may be giving that cylinder another re-ring before SDAC. Crap. Compression is down to 105 and there is a considerable more leakage than the other 3.
When I wet test it, compression comes up.
did you try the brakekleen ring seat trick in that hole?
Brian
No, I just ordered up a single cylinder ring set and new headgasket. Im hoping I will be able to go in there, clean up everything real nice, re-hone the hole and file up the rings and be done im time for SDAC. If not, ill just bring the Charger. I just dont want to do the brake clean or keep driving it as-is because the compression has actually dropped, so something is going on. Do you think brake clean is worth a shot? I dont want to score the cylinder up any worse than it is.
I was thinking about dumping a bottle of that "Restore" in as a last ditch effort and driving it until the rings show up. I have had luck with it in the past on old engines, but I dont know how it would do with a cylinder that hasnt ever seated.

i dunno, re-ringing it is probably the best choice unless many chime in saying the brakekleen trick worked well for them.
Brian
Yea....ive got the parts coming now, and i dont think it should take too long to re-ring it. Hopefully, it will cooperate for SDAC.
how did you do your break in process of the motor?
Turned the boost up to about 14 PSI and drove it normally.......which is beating the tar out of it.
