It was right at 3k rpm..........the car and myself could have went a 'little' more but the passenger brakes were in operation

On another note I filled up in Great Falls, MT and did 530kms to home with +200kms to go in fuel.......wow!!!

Herman.....let me take a quick look........brb

here we go; no vents off the drivers side cam cover, rear PS cam cover vent has restriction, front PS cam cover vent has NO restriction:

Herman K

Malcolm thanks for doing that so quickly you say there is no vent (elbow) from the driver side cam cover? so the hose that I see in the picture coming from the front PS cam cover goes under the fuel rail to the PS oil filler neck vent connection?

Sounds very good thanks for taking the time to do this.

Remember get your self a Porken clutch stop when you tackle you're master cylinder.

Malcolm,

Just a thought for you since you got these great results with your OCIC trip on fuel and oil consumption.

Run a compression and leak down test so you have a good base line of the condition as it now in case you want to have data for looking forward to the future with your car.

Great! Thanks for looking. That's like all the early GTS engines that I've seen. Exactly like an '87 to '91 engine....except for that "one year only" filler neck and hose that runs from the filler neck over to the valve cover.

I'm not sure what the engineers were trying to do in 1992.

GregBBRD

And while you are at it...remove the MAF, open the throttle, and see how much oil is sitting in the bottom of the manifold.

I also can check my '88 S4 which is another Canadian car.......if that makes any diff?

Herman K

Heheheh not to much Canadian bacon al at ones

the flyin' scotsman

no worries H.

yes and yes........no elbows on DS cam cover and the front PS cam cover elbow to the oil filler neck.

I ordered a new clutch master, blue hose and the Porken clutch stop........thx again for your generous offer in Kansas.

Prost........

you guys are too much

Herman K

My car has an accelerator on the passenger side.. hmm may that why I use some oil.. did get 350 miles out of tank of gas!

Parts on the way Malcolm - she will be as good as new soon.

Roger,

As Malcolm said that his GTS didn't require any oil to be added during his OCIC trip and as per post #32 he confirms that he has the PS rear elbow with the 6mm orifice restrictor.

If indeed he will find oil in the TB now (dependent on whether he will take the time to check this now) than this may over time lead to the piston rings in his engine to seize in the groves and thereby increase blow-by and oil consumption.

The fact that the GTS models don't have the drain back holes behind the scraper ring makes them more receptive than any other model 928.

So the prevention of oil in the TB is key even for those cars that don't use any oil now and the addition of a good cleaning agent such as Swebco 502 and recommended by Greg is good advice for 928 owners to follow.

no worries Herman I shall make the time to examine the TB and get to the comp and leak down tests.

My GTS engine probably has never had a trip since new that I just completed; 9 days and 6000 kms and 2 of those days it was parked at OCIC so this is a great opportunity to see what condition its in but I believe we know the answer

the flyin' scotsman

thx Roger...........you the man as always bro

for those following along the GTS required the clutch master to be bled in Great Falls (return trip) and I phoned Roger to leave a vmail just incase I may need a rush parts order and he answered the phone.........9pm Tues night

sorry for the hi-jack H
