Guys, mine has two belts as I have AC. Are there any recommendations for belt type size? Oriellys has two versions: Master pro: top width 12mm, length 905mm, and angle 36 degree Gates: top width 15 mm, length 926 mm and angle 40 degree I think the top width and angle matters more. Which one should I pick?

There are a number of unused, threaded holes between the bolts that hold the intake/exhaust onto the head. I need to attach a fuel rail bracket to the engine and I wanted to use a couple of these unoccupied holes. They seem to accept an M10x1.5 bolt; however, it only goes a turn and a half in and then stops. I don't want to force it and strip the threads so can someone confirm what size these holes are tapped to? It's not a 1.25 pitch as that doesn't even begin to thread on.

I’m building a little 1972 resto mod for someone. He wants to keep it automatic . I did some searching and realized the 83 turbo automatics had a lock up torque converter - badly needed really . I acquired one and on install DS from the 72 wouldn’t fit ( 24 spline -24mm) . The 83 zxt( at least this one) has a 26 spline output -26mm OD. I sold my last t5 DS and it had the oddball yoke - I believe is 26 spline . I’ve talked to many people that automatics and no one has one with a 24 spline output . Ordered a new yoke from Z Car Depot that they said had 26 spline . Came today and it was 24 spline 😡 I know autos are spoken about much , but maybe someone knows…

I'm having trouble finding .020 pistons and while I was waiting for some to come back in stock I was looking through "How to rebuild your Nissan & datsun OHC engine". The pistons in a 79-83 in a look to be the same as a 75 other than the rings, but I could be wrong. Will ITM RY6140-020 pistons fit? I have a n42 block and head. Thanks

One bolt broken, one fully loose but won't come out, and the pump housing itself absolutely refuses to come out. I can twist it slightly back and forth, but have made not even 1mm of progress getting it to come off. I'm trying to get this engine disassembled so it can go to the machine shop to be reconditioned, and I'm tempted to just have them remove the pump by any means necessary and replace it.

I’m trying to drop my oil pan and this is in the way I think. Is it a coolant drain? How would I go about taking it off? Thanks!

Hi Friends, so my coolant reservoir is at MIN at operating temp after some driving. Does it means I need to add more? Should I just top it off to MAX while it is running in the reservoir? Thanks.

So most of the regulars on the forum know I rebuilt an L-28 last year. With all sort of reasons for delaying the install I’m now about ready to do this. I wanted to start a thread to help lead me though any unknowns or challenges I’m bound to face on this next big task. To get everyone up to speed, the current engine has all sorts of problems that pushed me to just do a rebuild with a ZX motor I got at a salvage yard. Here are the bigs three items wrong with the current engine. 1. Rusted Core Plugs, so rusted that coolant leaked pretty bad. I had a temp fix of filling the rusted out holes with JB weld. It’s actually held. 2. Serious timing changing slap (needs …

Water Pump

It looks like my water pump is leaking. I'm getting ready to remove it and figure out what the problem is. I hope my video will allow somebody to affirm or not that it's my water pump? Also, any tricks to remove and replace? I'm sure those bolts have been in there for years, and probably need to be finessed? Any tips are welcome? IMG_7903.MOV

Hey Guys, My 72 240z began to overheat a few days ago while driving around town. So i've decided to overhall the entire cooling system (hoses, waterpump, thermostat, etc). My question is, go with an electric fan or use a new fan clutch and radiator shroud (the one MSA sells for the 240)? At first i thought going the clutch/shroud way would be cheaper, but after pricing it out, it's almost the same price if not more for the latter... Any suggestions?
