    Coolant in valve cover, could be EGR

    Hi again tony Thanks for your reply. Yes, the only places i can see coolant is two small pools in the corners at the rear of the head, and a little rim of coolant around one of the head bolts in the centre of the head, one cylinder in from the rear. I dont think the coolant was there when i...

    Coolant in valve cover, could be EGR

    Hi everyone Here we are again with yet another lost coolant / EGR cooling issue. I have only a small amount of coolant disappearing. I have chased this around for a few months now. I recently started getting a bit of sludge in my catch can (mann hummel provent 200, photos attached). The...

    Catch can mysteries

    So i think i found the problem... The inlet spigot on the catch can (where the hose coming from the valve cover enters the catch can) was crushed and deformed. Its a genuine mann hummel, but it was 7-8 years old and i must've over tightened the hose clamp too i think. I guess there was a...

    Catch can mysteries

    The thing worked perfectly for close to 8 years, with only the odd filter replacement. It seems like a big coincidence that when the external over-pressure valve was changed to internal the catching water instead of oil thing happened.. If i pull the filter out, there is no water in the catch...

    Catch can mysteries

    Hi all, Ive had a Mann Hummel provent 200 on my 2007 yd25 d40 for around 7-8 years. It has as always worked as it should, i was draining out around 50ml of oil every month or two. Then one day around a month ago, the rig started blowing lots of blue smoke out the exhaust that smelled like oil...

    D40 timing chain tensioners - which part numbers?

    I didnt realise you're in NZ, i agree $2k is a lot. by the looks of it the current genuine nissan timing chains are made in Japan thats good news for sure I had about $10k spare when my car went bang ( and i needed nearly $8k of it), as a near new STX d40 purchase price was about $10k less...

    D40 timing chain tensioners - which part numbers?

    The timing chain on my 07 spainbuilt STX snapped at 70,000 k's, so i feel a sense of duty to weigh in here Im pretty sure the spanish built 05-09 STXs had a timing chain sourced from a company in France that was under spec for the job, hence the high (ahem) number of timing chain failures and...

    Best brand of cvs to buy

    I bought GSP CV joints recently and fitted them to my 1998 Mazda Bravo. When the d40 CVs start to play up Ill definitely be using GSP again. I priced genuine Mazda CVs from the local dealer and as expected the price was beyond ridiculous. GSP seem to be known in Australia as the best...

    ABS light dramas

    I dunno about that. I wouldnt think a bit of grease would cause a problem because the sensor is detecting conductive metal rotating past it My wheel sensor was pretty greasy when I replaced it That wasnt the problem though, the problem was that the sensor coil had broken and was open circuit

    2010 ST-X Limp Home - EGT error codes

    Not sure if this is any help, but ill put it out there I got limp mode in my 07 STX a few years back I pulled over and scanned for fault codes on the spot with the Torque app and OBD dongle It came up "suction control valve jammed" straight away, clear as clear So if it is the SCV, you can...

    ABS light dramas

    I replaced the ABS sensor with a $30 ebay special yesterday. The ABS light went straight off once i cleared the codes Nissan quoted me around $320 for a genuine ABS sensor. Im all for genuine parts, but bugger that for a simple little magnet with two wires attached Re the gearbox codes: i...

    ABS light dramas

    Not sure about gearbox info, i think thered have to be fault codes stored to find anything I removed the rear left abs sensor and found it open circuit OBD for the win again Goes to show those abs sensors can just fail internally with no damage to wiring or incident to explain why it died
