R33 Engine Problems

Recommended Posts

my r33 gtst is un happy at the moment. the second water related hose has let go within a month. i am almost up for a timing belt,water pump change and she is due a service and tune. on the way home today after replacing the water line at the rear of the engine i was loosing power under boost, the revs where fluttering up and down and there is a groaning type noise . i also noticed that the vacuum section of the boost gage was registering lower than i have ever seen. is this miss firing spark related and can anyone shed some light on these problems thanks

might be worth checking the oil and coolant. make sure neither are milky. also look at the coolant with the engine running. if there are any signs of bubbles then you may have a blown head gasket (also if you are losing coolant).

Did the engine overheat at all?

Did u bleed the colling system after u replaced the blown hose?

Is the problem always there or intermittant?

engine didn't over heat i had only driven a short distance and realised something was wrong

the colling was not bleed but there is a fair bit of rusty looking residue where the hose has sprayed in the engine bay

the problem is intermittent but its only just started happening.

when the first hose went i thought i may be up for a head gasket but got lucky when it was found to be a split under side radiator hose. all the hoses are a bit crusty getting on now.

any idea ?

there is no milky looking stuff, radiator could do with a good flush. hope im not up for a head gasket as well as the rest of the things that need attention.

    • TCU is enroute, should be here on Monday. Have just paid for a transmission locally, they've got to pull it out of the car and should be with me on Friday. Just getting little bits and pieces I need for wiring. Thinking about using a small bulkhead connector to run the transmission wiring through the tunnel as the trans plug is quite big.  So all going well i should have the box dummy fitted up next weekend and start wiring.
    • sure, just PM me your email....
    • Haha likewise, take my shit box for a spin and maybe you'll end up wanting a R33 shit box again lol...  
    • @Jasoncauser looks like a tight technical track, and definitely fun! Let's hope I make it to that day 😎  
    • The springs just lets the valve bleed off pressure/oil and it bypasses the feed gallery and heads back to where the pickup feed is On the LS the oil gets the the bearings...eventually  This vid explains the OEM pump well IRT the pressure release valve and how the bypass works The oil pressure light coming on intamitantly could just be a sticky valve, but, why pull something apart and not put something better in  I believe the low oil pressure light comes on somewhere between 5-10 psi Well will stick a gauge in after the installation to see what difference it makes at hot idle and higher RPM, and by high RPM I mean 6300 RPM.....LOL
