If anyone has the tool to do a compression test to my car and can come up to my place an give me a hand, I just dont want to drive it, in case it blows up on me or something.

Its got biblical ammounts of oil in the intercooler and pipes (blow-by) and its dropping oil pressure badly.

So, help a fellow member! , remunerations in the form of your favourite alcohol beverage, are in order. :devil:

Cheers

Ric

A long time? what's different between an rb20 and a 25? a 25 doesnt take long to do. remove crossover, coilpack cover, coils, injector crank it over.

Is it a redtop or a silvertop? ECCS or NICS?

I'm sorry I don't have the tool Richo but maybe give James from TypeX Motorsport a call:

He's a good bloke, can do anything with any engine. might be able to help you out, but naturally he doesn't work for free. If it's only the tool you need then it shouldnt cost you much.

Whats this tool we are talking about? is it like a gauge or something,

Do you need a different tool to do a Leakdown test? or the same does the job? Sorry for my noobiness the first time I have to worry about the engine on my car.

Cheers guys

you want a screw type compession gauge. Around $30-40 from any automotive store.

also id say its not piss easy, considering most cars it takes about 5-10mins for a compression test, it takes like an hr to do a compression test on a rb. take of crossover and all pipes, remove cover, remove coilpacks, test, etc, put it all back together

Richo, it's a screw in guage that you screw into where your spark plug was. Theres no point in doing it yourself if you don't know what you're doing. As Enrico says it would take you over an hour (if you didn't have help from someone who's done it before), but if someone with the knowhow can help you out it will take 20-25 mins. Leakdown test is completely different.

If you're an RAA member you can call them and ask them to do it for you, if you need a mobile service. Get a quote first as to what it would cost you, but I assume it wouldnt be cheap. about $100 or so.

Yes I know its pretty bad, maybe time for a new RB30/RB25 and new turbo to suit :) *looks at very empty wallet* :D

Mike: I was behind you getting into the city carpark today, I remember your car because of the RPM sticker on the side, it was you wasn't it?

you obviously dont work on rb's alot or lack experience. its just as fast as doing a compression test on a sr. i do both all the time.

I can't possibly see how it is just as fast to do a compression test on an RB compared to an SR. The SR you can literally be done in 10 minutes. On the RB you haven't even gotten the darn rocker cover off by then, well on a NEO anyway. POS.

I have a compression tester tool if anyone needs to borrow.

Why you taking the rocker cover off? I'm assuming you mean the valley cover, mine hasn't been on for the last 2 years. ;) And NEOs well they've got that lovely plastic turtle shell too.

Also when does time equate to difficulty, I never said it was necessarily quick, who cares if it takes him an hour or even 2? This isn't a WRC service stop.

lol!

Mitsu RalliArt team: ok boys, we got broken rear suspension, engines running rich, air intake filled with leaves, radiator is ~ 80% clogged and we have 3 inch tread missing from rear right tyre... and we got 37 minutes to fix to the next stage... lets get to it!....

Rico: Ok... compression test... want it done in under 25 minutes... neighbours is on at 6:30pm...

Guess which one gets everythin done within half an hour first?

jks :P

Yep that was me!!

my rpmlounge.com.au stickers do me proudly :P

Also I would help out but a) I don't like doing anything to anyone elses engine, because i dont want to be responsible for any f**kups.

and b) you said you need it done urgently and I'm full on for the next few weeks. I don't have any spare time I'm sorry! (I write on the boards when im at work)

Its all good mate. no worries. One thing though, can something actually go wrong while doing this compression test?, just want to be aware of possible risks, and see if I can avoid them.

So the Rocker covers stay? just need to get the valley cover off, is that right? then get the coilpacks and

coils out to expose the spark plugs and finally remove them, yeah? Shit I am so useless. hahaha

      Mistakes were made, my R34 Story

      The oil pressure sensor for logging, does it happen to be the one that was slowly breaking out of the oil block? If it is,I would be ignoring your logs. You had a leak at the sensor which would mean it can't read accurately. It's a small hole at the sensor, and you had a small hole just before it, meaning you could have lost significant pressure reading.   As for brakes, if it's just fluid getting old, you won't necessarily end up with air sitting in the line. Bleed a shit tonne of fluid through so you effectively replace it and go again. Oh and, pay close attention to the pressure gauge while on track!

      I don't know it is due to that. It could just be due to load on track being more than a dyno. But it would be nice to rule it out. We're talking a fraction of a second of pulling ~1 degree of timing. So it's not a lot, but I'd rather it be 0... Thicker oil isn't really a "bandaid" if it's oil that is going to run at 125C, is it? It will be thicker at 100 and thus at 125, where the 40 weight may not be as thick as one may like for that use. I already have a big pump that has been ported. They (They in this instance being the guy that built my heads) port them so they flow more at lower RPM but have a bypass spring that I believe is ~70psi. I have seen 70psi of oil pressure up top in the past, before I knew I had this leak. I have a 25 row oil cooler that takes up all the space in the driver side guard. It is interesting that GM themselves recommend 0-30 oil for their Vette applications. Unless you take it to the track where the official word is to put 20-50w oil in there, then take that back out after your track day is done and return to 0-30.

      Nice, looks great. Nice work getting the factory parts also. Never know when you'll need them.

      I take it that the knock retard is from bearings tapping a little tune? Thicker oil is a fragile bandaid. You need a much bigger oil cooler and probably the bigger pump being discussed.
