Just providing a data point for people. 95 GS-R, 128K miles. 45 track weekends including wheel-to-wheel racing, and bunches of autocross runs. Uses probably 3/4 of a quart per track weekend. Compression numbers:

1: 225
2: 210
3: 225
4: 228

It's getting a little tired but certainly isn't terrible yet.

 

da ubermoteur!!!!

lookin good, Shultz! I think you got the 1 in a thousand motor.....

keep it up man
keep oil in her.

I also have a high mileage motor near 200k miles (hence my nickname). Compression test was not accurate. So I did my own leakdown test...

Cyl#4 - 98.5%
Cyl#3 - 97.8%
Cyl#2 - 97.8%
Cyl#1 - 98.3%

 

Yes yes, a leakdown test is on "the list." Those numbers look very good BTW.

Another data point from this past weekend (number 46):

- 2 drivers at an HPDE
- 130mph entering T1 (Roebling Road in Georgia)
- 3rd fastest time of the day (with codriver driving - I went off )
- Oil usage: 0.5 quarts

I feel like I should send a Thank You note to Honda.

 

speaking of leakdown tests.... I came across this link: http://www.lafishmag.com/LeakDownTester.html that shows how to build your own leak down tester.
I priced the parts:
Sears air line regulator: ~25$ (www.sears.com, part #00916025000)
Spark plug hose: ~$15 (powerhouseproducts.com, part #POW301013)
Coupler/nipple/teflon tape/etc.: $10 (Lowes)
Total: $50 - compared to a (nice) Longacre for ~$100, or a dealership charge of about $150...

hth.

 

Karl,
What kind of oil are you burning? regular or synthetic. cause if its synthetic then i *really* think that hoa should get a card this x-mas.

Mobil 1 5W-30 since 1000 miles. Up until recently I always used Honda oil filters - recently went to the Mobil 1 filters. I show up at every track event with fresh oil and a fresh filter, and have always done so.

SJR: Thanks much for that link. Gives me an excuse to go to the Sears at our pimpy new mall.

 

no problem Karl - anytime I can contribute to the addiction of a fellow man/woman and the shaking of his/her money tree...

 

Well, Sears had only a subset of the needed parts. Off to sears.com I go to spend still more money.

 

so what did Sears not have? I was re-reading the how-to page, and the guy mentions ripping out the Schraeder valve. Hmm, is that necessary? 'cause if you leave the schraeder valve in it, then if you get a separate gauge (that goes higher than the one that comes with theh regulator) and hookup and bada-bing, you got yourself a compression tester. Of course, for $12, I guess you can just buy two of those adapter hoses - or you can make your own by using an old spark plug and gutting it - but that's really trying to be cheap
anyway, just rambling... and thinking that I have a 15 year old 6.9L diesel that could use a compression and leak-down test - except it ain't got no spark plugs! I guess I'd have to use the holes of the glow plugs... this is almost as much fun as getting on a track. (at least that's what i keep telling myself until the day I can go back to a track - sigh! jonesing sucks azz)

 

Keep it simple. Go here..

Although the author didnt know what the valve thingy was called, his write up makes it easier.
