Hey guys. About three months ago I did an oil change and poured in some 10w-30 VR1 into my 280z. Two weeks ago I noticed the oil pressure is a bit low for my liking. (it sat about halfway up at acceleration, usually it sits just under 3/4). Anyhow I pulled the dipstick and to my dismay it was VERY low. Went to the local NAPA and bought two quarts. Poured on in one and was on me way. (oil registered great). Today I checked the oil once again and it was again getting to the L on the dipstick. I've driven about 300-350 miles since the last fill up. I have don't have any white/blue or any other colored smoke coming from the exhaust. The exhaust doesn't smell like oil at all…

I had to pull the head on my L24 to change the blown head gasket. Two of the head bolts broke off. I didn't have the time or the tools to deal with that, so I took it over to a local engine builder. They did a nice job on it. Today, I want to put everything back together. I noticed that the cam has moved out of place from where it was when I took it in to get fixed. I can't seem to get the cam to rotate. That seems odd. I did not want to force it. So I have a couple of questions. What is the best way to rotate the cam? How much force does it take to rotate it? Also, does it spin in only one direction? TIA, Marty

Pulled my old water pump on the 78 280Z and I had 4 bolts of various sizes. One was bigger then the other three. The other three were of the same size but of different lengths. Does this sound right? I'm wondering if I should have had 5 bolts holding in the water pump. Am I missing a bolt or does the 4 of various sizes sound right?? Thanks. Jeff Woodard

So I found a 73 240z for sale in Oceanside that's been for sale for quite a while becuz in my opinion the seller is asking too much. I talked to him today, got some good information. I'll put the link below. Here's the scoop: - 3 liter stroker made from an L28 block with ported E88 head and a hot cam. - 5-speed transmission out of an early 80's 300ZX turbo - R200 LSD http://sandiego.craigslist.org/csd/cto/1604300964.html All of this information is at his word. Obviously one cannot pull the head off the engine to look, but are there ways to visually tell if the diff and other things are legit? The seller is pretty fixed on getting his asking price for the car despite a…

On the S30's there is a bracket welded to the firewall that contains a spindle (pivot point) for the first of the many moving parts in the throttle linkage. This spindle has 2 bushings similar in shape to the ones that the shifter lever connects to the tranny with (totally different size though). The bushings are plastic, and in my case, they allow quite a bit of slop as the accelerator is moved. Has anyone ever rebushed these? I'd like to find either a final bushing or one I could use as a starting point and grind/mill down the the correct dimensions. Also, I'd prefer metal over plastic. Thanks.

Radiator had a leak so I pulled it and am taking it to be boiled out and fixed. While it's out, are there other things I should consider addressing? Car has sat for about 6 years. I am doing new hoses and thermostat. Belts? Other? All feedback appreciated. Thanks. Jeff

Have any of you guys ever disassembled a throttle body from a 75. I'm talkin about completely! I need to take one apart as far as possible without getting it out of adjustment in order to completely clean and cosmetically restore it to better than new condition. Any ideas/suggestions? Thanks Bryan

I fabbed up a crude snubber for the front of my R-200 differential, since I knew that the diff mount was showing signs of end-of-life (visible debonding when pried on with a screwdriver off the car), and found that it eliminated a bad clutch chatter problem that I was having. I assume that the weakening original rubber diff mount was allowing the front of the diff to bounce up and down at low acceleration levels, causing the clutch to stick and slip, ie chatter. Just putting this out there for anyone that may be having a clutch chatter problem. Something to look at. My clutch and pressure plate are brand-new, properly installed and broken in, but still chattered if I t…

I have a 1974 everything is stock but the dual webbers. I found a good deal on some so I only have the adapters and carbs. The thing I am needing is the throttle linkage. Do I need to buy one. Or will the stock work and i'm just an idiot and can't hook it up right. And if I need to buy one then where from. I have searched the net all day and can't find just the throttle linkage. And just if I did not explain good enough. I need to hook up my dual webbers to the gas pedal. Thanks

Well, I talked to the guy who is changing out the u-joints for me. I was thinking about doing it myself, but I didn't feel like torquing on bolts with the car on jackstands. (A scissor lift is in my future, I hope.) I guess I should have at least taken time to inspect the driveshaft. He found two bolts missing and another was finger tight. VERY bad on me. I should have taken a closer look at all of the undercarriage when I bought the car. Anyway, I am still going to try to use this as a reason to push the scissor lift past most of the furniture my wife wants. After all, it's all about safety, isn't it?
