Ok so i did a compression test today. 116,500 miles . the results are

#1. 220psi
#2. 218psi
#3. 220psi
#4. 238psi
does this sound right i notice on cyl 4 the spark plug has a lil oil around the threads from the top down but none on the tip . This was after sitting all night . The car burns about 1quart every 1500-2000 miles driven very hard . Just made 208 whp on a dynojet with 70mm tp,70mm exhaust and vafc, stock intake. I was just wondering if similar results were found on cyl 4 i think i might need to replace my valve cover gasket , the ring near the oil filler might be seeping into the plug tube. so a lil oil run down over night could give me a slightly higher reading right . also pretty much no leakdown at all.

 

yeah everything looks good. if you had some oil leaking into cyl 4 then itll bump compression #s for sure.

 

shouldnt this be moved to maintenance?

 

Nice numbers. My buddy just picked up an 05' S2k over the weekend and he wanted me to do a compression test for him. He got 225, 225, 225, 230.

I'm scared to do mine

 

i did mine last week its an 07. I got 225 170 160 190. can you say new motor soon.....

 

OUCH! what have you been doing to ur motor..

 

wow thats saying stroker here you come 2.5 inline pro kit

 

about 6-7,000miles of track useage and really agressive street driving.

 

Your compression is lower than when I had a 3mm hg on my old f20. lol

 

doubt you need a new motor, just a new head. the valve guides blow ass on our head. do a leakdown and see where the problem lies. then rip the head off and send to head shop. youll most likely need all new guides, and valve job. pretty normal im finding out. i have two with crazy compression numbers here in town. one apart in my shop now. whatd we find, exh valves that werent seating, and all trashed guides with one broken. I have a bad ASS cylinder head shop that i use here in vegas. they have done many world record honda heads. so if you dont have anyone, and dont mind mailing the head, let me know and ill have them do the head for you. maybe even port and polish while you have it off.
later dave
