Can you run to much OIL pressure,

my brother's mk3 RS Turbo as just let go whilst on it's first run.
The turbo was bought brand new about 3 years ago from Turbo technics and is there stage 3 version, tonight was it's first real ride out as after 5 long years he's finished his rebuild.

Now the Turbo as only done 27 miles, yes 27 and just spat oil all over the bay, he as fitted an up rated oil pump and from cold idle the pressure is about 75psi and on warm idle it's on 20 psi and when rev'd at 2000 rpm cold is 80 psi and warm is 40 psi, is this to much pressure or is there an issue with the turbo, although after 3 years warranty means nowt

 

Those oil pressure's won't hurt the turbo

 

Check oil return from turbo isnt blocked/coked up, its a common thing!

 

ta boss,

i'm now nicking yor sig, lol

 

So, thats 2 of you with over-sized sigs then!!

 

i had too much oil pressure when i had a faulty cosworth oil pump and it burst the oil filter

 

me too!

and it fucked the big ends.

car didnt even start, that was just turning it over!

 

mine was ruunig fine ,i drove it around the block came back for a little check over ,opened the bonnet and gave it a little rev and i could see the oil filter changing shape then BANG oil everywhere....including in my face...and it was hot

 

Blame 'benni' if you wish as he did the sig but don't you have better things to do?

 

lol!

when it happened to me id never heard of ANYONE it happening to before. maybe we should start a club

mine was i dunno, 2001 maybe? fresh rebuild in the 3door, think i may have still been running it in. went to start it but it just turned over, didnt start.
got out to check under the bonnet and the oil filter had blew and was oil everywhere.
presuming it was a faulty filter i went n got a new one and a load more oil and it did it again!
then once engine out n checked it had caned my brand new fucking bearings

 

what did cosworth say?

they gave me a new pump great ,what about a new face ,cleaning all the mess ,taking the engine out to fit the new one

 

i thought i was the only one who had that happen to them

i was told to "strap the oil filter"

 

 

i cant even remember, some lame excuse i think

cheers lads, your excuse really comforts me in this time of extreme wallet raping

 

all because they let the work experience lad work the machine on that day

 

lol we had a couple in last week, and knowing their skills, id say you prob right

 

Martin, I apologise, I have informed that Traders are allowed 100k. So one of these for me......

 

i spoke to Cosworth today about this.


And Jeremy said a couple of years ago they had a batch of 100 made,
20 of which were faulty as had no hole drilled in the relief valve, so over pressured.
But only 5 had been sold before it was noticed, of which only 2 had been fitted and run up.

 

surely not mine and jtechs?

 

Well i thought it sound'd ok, as i knew Jtech had a issue, as he told me last week.

But when i read you did too,

 

Mine was aaages ago, 2001 or 2002 i think, never known it to happen to anyone before, or since, till jtech

 

stav,
you know what is ok pressure on compression check on 200sx?






carl

 

as in cyl pressure? no soz mate, sure thats an easy search on SXOC tho.

obv different depending on if its a UK S13, Jap S13, or S14

 

ok cheers



does 170 psi sound about right?
s13
carl

 

sounds almost too much, so yeah, deffo fine.

and basically, like most cars, if they all fairly equal across all 4, you know its healthy enough.

its not cyl pressures thats a problem on S13, its fucked big ends.
