hey all,

as the topic states my dipstick keeps blowing out. has anyone ever experienced this?

i had a quick search and nothing came up, also another thing to add is one of my belts is squeeling real bad when i go full throttle, i just had the belts replaced, was thinking that maybe my oil pump is seazing up causing the belts to squeel and excess pressure in the oil gallys,

the dip stick has blown out 2 or 3 times now, its annoying as my engine gets covered in oil everytime it happens, could someone please shed some light on why this could e happening

thanks

mitch

EDIT: forgot to mention its an R33 GTS-t

had this problem alot... at first it was because my catch can was setup rong.. so sort out your breathers and check if theres too much gunk built up in your rocker cover breathers and baffles...

The squealing on full throttle may be your exhaust manifold gasket.. Thats a common cause that alot of customers complain about when they say "belt squeal"

Also get a leakdown test done and a comp test done.. Because another reason may be too much positive crank case pressure, eg: rings are rooted, ringlands broken, pistons melted.

So thats a rough guideline to follow..

yeah exactly as above, my experience has been that its either

- catch can incorrect

- your engine is f*ked

i'm hoping for your sake that you have recently installed a catch can

if not, its time for a compression test and leak-down test and bring your wallet..

WOW, thanks for that fellas, would never have picked the squeal to be my exhaust manifold, my mate keeps telling me it sounds like ive got a leak there.

LTHLRB: no i dont thrash my car really, im lucky to hit full throttle once or twice a week, ive only got a 5 minute drive to work now so the car probly doesn't even warm up properly anymore, but the problem started about a month ago before i got this job. for the last year ive been doing 100 k's a day up and down the freeway

ive been running 10psi since i got the car, previous owner was running 8, at 10psi it creeps a little to 11psi

with the squeal i thought it would be the belts cause it does it on start up occasionally

does anyone know any good workshops around castle hill/baulkham hills? ive only just moved down here so im still new to the area

yeah i had this problem as well when i first got my car, it kept blowing dipstick out it was caused by a stuffed piston had a hole in it.

is your car still running on all 6? if it is it could be worn rings. Hey if ya want to ya could do a compression test ya self and buy a compression tester from autobarn or supercheap one what screws into your spark plug hole. all ya need is that a pen, paper and ya normal tools to get ya spark plugs out.

If ya want to check if ya piston rings are worn is to put a drop of oil down the spark plug hole, thats called a wet compression test it helps seal in the combustion pressure. good luck man hope its just ya catch can

thanks LTHLRB, what do you use to lube the belts up with? im going to do it this weekend, its too dark when i get home during the week

madevo3: how much is the compresion tester to buy? i think it would be a good investment

ill be checking my rocker cover breathers aswell, i hope thats all it is

thanks again for your help

hi, well i tightened up the belts, that seemed to stop the squeeling, also i found out i have an exhaust leak, im not sure if is from the exhaust manifold or the dump pipe, is there an easy way to tell?

also where would i get the gaskets from? i think i might just change them all

cheers

sweet thanx, i thought you could get them there, just wanted to make sure,

when you say they're not cheap, how much do you think they will be?

Don't worry about the gaskets until you find out if you need a new engine.

    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell. 
    • Final update!!! Got the front bar fitted and sprayed and all sorted now. My cutouts worked great and the indicators aren’t just falling off. 😂
