I don't have one or remember having one. My FSM shows an oil thrower. Could there have not been one or did I lose it and my mind? It's an early '77 with a 2 row pulley. MSA has one for $1.70 for '70 thru '83 but no other parts places have a listing, Courtesy either. Will it really cause the crank seal to leak if I don't use one? 3 woodruff keys, chain sprocket on 1st, worm gear on 2nd and the pulley's on the last one. Everything seems nice and snug sitting on an engine stand. Thanks for any help.

I've got a new oil pump on order for my Z and it should be here soon. While waiting for the pump, I've been searching the forum for info about how to prime the new pump after installation, and I've found some threads that talk about it, but I'm not sure I get it. I got the general procedure: Bolt the oil pump to the block and then spin the pump with a drill from above down the distributor hole. But... It's my understanding that the distributor drive shaft has to go in from the bottom before the pump is bolted into place, right? And if that is the case, if you try to spin that shaft with your drill, you would be trying to spin the engine with your drill, so... Of course, I…

Hmmm, I filled the '71 with coolant for the first time yesterday and just noticed a slow leak from the bolt on the bottom of the water inlet. I will take it off tomorrow to inspect but I don't recall any mating surface or corrosion pitting issues ... and I used aviation gasket sealer on all surfaces. Anyone ever see a leak in this area before?

I have a 78 280 z and have the engine out of the car. While the engine is out, I want to replace the front seal on the automatic transmission. I have studied the 4 manuals that I own and none give good instructions on how to remove the torque converter and replace the seal. Please help: 1- Does the torque converter just slide forward for removal? 2 - Should I be prepared for fluid loss after the converter is removed? 3 - are there any special tricks to replace the front seal? Thanks in advance for the help

Soon I'm planning to change the exhaust manifold & replace the exhaust manifold/intake manifold gasket. I also need to replace some of the studs that come out of the head because some are too short, which I think has caused my intake manifold to leak slightly. 1st Question: How should I remove the existing studs from the head? I'm worried about breaking them off by not removing them correctly. 2nd Question: Should I use a factory Nissan intake manifold/exhaust manifold gasket? Or is there a better one i should buy?

I put my timing stuff on and was very careful. I turned the crank over and now the crank sprocket dimple is 2 links to the left of my bright link. Is this normal? Kinda' seems like it since the crank sprocket has less teeth than the cam sprocket. Motor turned like rubbing panties together.

I have been researching different sites but still can't find anything on a cam someone is selling here locally and I haven't heard back from the seller. It's a NOS part and I think they were made in the 70's. It's never been installed and I wanted to do some research on it but have had no luck. Any leeds would be appreciated. Thank you.

I have recently completed a 3.90 R200 diff swap into my 71 240z and also purchased a techno versions diff mount which I believe is very similar to the R/T mount. I also purchased the poly GM mount so I can get rid of my factory lower mount. The problem I am having is that I cannot get the bolt lined up to attatch the gm mount to the steel bracket. If I bolt the gm mount to the bracket first then I'am off at the diff bolt holes. Has anyone with this diff mount had to modify their's to make it work? it also seems as if the poly mount needs some trimming done to it aswell. I have read multiple times that this is a straight forward install, and I have triple checked everythi…
