I have a S12 VG model, so the motor is slightly different, but maybe you guys who have worked on the non-interference motor with W series heads may know what I'm on about here...
I started up my car after about 1 month of non-use. Battery was dead (of course) but the thing started right up after a jump. It was really bad ticking at start-up, but not as bad as a diesel or anything so I let it idle for about 1.5 hours to charge the battery.
I came back after the 1.5 hours to find the motor still idling loud. It sounded like the valves were tapping pretty loud to me. Is there a known issue with the VG W series heads like this? Is there anything I can put through the motor putting off the head change?
Perhaps I should check the pump or the channel to see if it is clogged a little? What do you think?
Valve ticking VG30E
Re: Valve ticking VG30E (Dattebayo)
mines doing the same thing, but theres no oil pressure lol.
Re: (Dattebayo)
ack! where is he?!? from what i understand, valve ticking is pretty common for our engines..i let mine stall one night after some galavanting in a mall parking lot.. when i started it back up, it did the same thing. id never heard it before so i left it. when i picked it up the next day the noise got louder, and there was no oil pressure.poking at the intake cam from the oil fill doesnt fix it.. i tried that already.Dattebayo wrote:O NO LOOK OUT! It's "that" guy!
Yeah, my oil pressure was kinda low too, but it was at idle...More info to follow tomorrow when I get back from work.

This stuff is really good. I used it on my VG aswell as others.http://www.z1motorsports.com/p...f63f8
Re: Valve ticking VG30E (HomelessRonald)
Adding half a quart or more of 20-50 weight synthetic blend oil might help, and then convert to full 20-50 weight synthetic blend next oil and filter change.
Re: (Dattebayo)
Don't know how similar your motor is to a VG30DE, but I onced parked my J30 due to leaky water pump and waited a couple of months to fix it. I had to move the car every couple of weeks and before long I was more concerned about a loud clicking sound every time I started the engine (with about 167K miles on it), than I was about the leaky water pump.Dattebayo wrote:Synthetic? Yuck. I don't have enough invested in this car to justify spending that much on oil. Will dino oil be just fine? Also 20 is a little high. Are you sure I should be using such a high number? The highest I used in my turbo Z31 was 15-50...
After I replaced the water pump, timing belt and all, adding half a quart of 20-50 synthetic blend quickly quieted what was apparently a sticky lifter. The best $5+ I ever spent and synthetic really is more slippery. Next oil/filter change I switched over completely.

Re: (GerryO)
Not similar at all in terms of valves. The only thing a DOHC has in common with the SOHC is the bore/stroke of the cylinders/pistons.GerryO wrote:Don't know how similar your motor is to a VG30DE
Sorry.
