Keeping That Engine Alive

[T04GTR]

for the street/old pac drivers. and for the track.

due to a couple of friends of mine loosing there engines from a simple lack of oil i thought id post up a easy guide on how to keep your engine from poping...

GTR OWNERS: when you change your oil, fill the carnt thing up to the hump on the dipstick.

this works out to be roughly 6 to 6.5 litres of oil.

if the oil level is on high. it will surge just acelerating in first gear. (not to mention corners)

i have done thorough testing of this and can asure you all that this quantity of oil is the MINIMUM that is required to combat oil surge in a standard sumped gtr.also a tomie baffeld one to.(makes no differance if its

baffeled or not.) (mechanical oil presure guages dont lie)

now. im not a fan of motul oils. but hey you guys love the shiet so yeah.

using a good quality synthetic oil with a cold rating of less than 15. and a hot rating of 50 or more is the go.

eg 5w60 penrite is my personal favorite. its the only one i have used that can stand up to a whole track day without "breaking down"

GTS-T OWNERS your cars have a much better sump design so you can get away with using abit less oil. 5.5-6 litres of oil is suficant. the rwd sumps still have poor bafeling anyway. so fill them to just before the hump on the dipstick.

so summing it up PUT OIL IN YOUR ENGINE its not hard to fill er up abit over full. it does no damage to the engine. it just keeps all those legs in bed.

so following this instruction it will extend the life or your RB by a long mark

the same rules aply to any RB powerd car with the standard CAPACITY sump

ps.. moderator please leave in nsw section as it is aimed at our own circle. cheeres

But you don't recomment this for the street do you?

I changed my oil recently and as I had a track day coming in a few weeks I overfilled. Car goes fine, a bit more oil in the catch can (or spewing out of it in my case since it is a crap can) but the one thing I noticed is that when I start it up in the morning (or stone cold anyway) it burns oil for about 3-5 minutes. I can see it coming out the exhaust and my garage fills with fumes.

It didn't do this before. Can you explain it and is it ok?

[T04GTR]

this is for the street. and the track.

your excess smoke is probably due to oil rings/clearances not yet setteled

my 200000k old gtr doesnt do it. nor does it fill the catch can.

[Guilt-Toy]

what about a RB30DET with a rb30 sump ???

[T04GTR]

yes. the same aplies

[Guilt-Toy]

yes. the same aplies

Mine has a oil controll problem at the moment... we built this RB30DET over 2.5 years ago and we did not know to block one of the oil feeds and put a restrictor so if i had more oil in the engine i would have an oil fountain lol

getting this done in the next month or so

Dave,

What about installing a surge tank?

Would that be better for GTR's on roads like OldPac and Macpass - or track events?

i think you may have wire crossed steve-o. surge tank is used to combat fuel surge. there is no realy way to add an external surge tank for oil without going dry sump, in which case it's still not realyl a surge tank, just an oil, holding tank.

generally sump baffles are the way to go to help combat oil surge as they attempt to prevent oil from flowing away from the pick-up, or even better a larger sump and baffles, or at the extreme, dry sump. the only reason not everyone has them is fitting the sump baffles requires engine removal.

Yeah i thought that just after i posted it up - couldnt be bothered deleting it

Thanks richo - so far no fuel issues (touch wood) other than that damn fuel cap - it started leaking again today !!! but its only on very hard cornering

[T04GTR]

get a commodore one. part number 86ULP from ANY SPARE PART SHOP

you wont get any more oil up there than normal. instead you will be pumping oil thru the motor not air!!

this is what people dont understand...

but if you wanna pull the head off to try and kinda make a diferance go rite ahead

Turbine and I just pulled my GTS4 RB20DET out this weekend and found that 4& 6 BigEnds were totaly cooked and stuffed from lack of oil.

Have had clattering noise for some time now and oil gauge always mostly reads very low but sometimes full scale so just dismissed the oil gauge sender as faulty which is common fault have been told.

Mostly filled to under high level so prob not enough for AWD GTS4 which has same sump as GTR & Stagea.

Over filling probably may not have saved my RB20 but it may have made it last longer so I will be filling my next motor up higher.

I am looking for a Stagea RB25DET if anyone knows of a near complete motor less Gbox.

Dave why the thumbs-down for Motul? I'm not a Motul fanboy it's just that I have 5L of 10W40 sitting in my garage waiting for this weekend.

Well if GTR's suffered from oil surge... this thread would actually be right

But they dont, the sump design is actually quite good.

The killing of bearings etc is due to other reasons, certainly not oil surge

A topic comes to mid actually... i love the search button

What oil is best for a 33gtst with only a turbo-back, front mount, pod and boost controller?

What oil is best for a 33gtst with only a turbo-back, front mount, pod and boost controller?

Try doing a search - there's a million threads on this (particularly in General Maintenance and Forced Induction)

For the record, I use Elf Excellium 5W-40 Full Synthetic

In saying that, I think a fair few people on here use Motul 300V Chrono, 8100 Excess or 4100 Turbolight - there's many to choose from that will do the job. Do the search and figure out what suits you best.

I guess it comes down to how much you want to pay, how modded your car is and how you use your car (i.e sunday driver, daily commuter or weekend warrior for example).

Update on an oil problem no-one could have fixed!

Found the reason for my oil problems - the back plate on the oil pump had come virtually off and most of the screws had come out!!

As this is inside the AWD sump and needed the complete block top be removed to identify the problem.

HOT DAMN!!

i though everyone who went to the rack new this
