Dip Stick Blowing Out

[weeman1]

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..

[WazR32GTSt]

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..

[LTHLRB]

wallet and the latest VPW/rocket cattalogue for your rebuild parts

do you thrash your car much? how much boost have you been running?

[weeman1]

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

[LTHLRB]

yeah mine used to squal when the exhaust manifold gasket was cracked.. then it gets worse from there..

tension and lube all your belts aswell

[madevo3]

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

[weeman1]

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

[WazR32GTSt]

best to get a compression test at a mechanic

if you don't do it 100% right you are going to end up with weird results and have to take it to a mechanic anyway

its a once in an ownership test really

[LTHLRB]

go out to your local bursons and repco and ask for DRY LUBE.. should come in a stick.. not its not for sexual needs..

[madevo3]

it should only be about $50 at the most,but if ya not sure take it to a mechanic

[weeman1]

thanks for all your help, ill get it sorted this weekend and ill let you know what happens

cheers

[weeman1]

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

[Habler]

You can get them all from Nissan. They won't be cheap but they are genuine.

[weeman1]

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.
