I moved this from the Tech forum, posted it there by accident... I was just wondering how long it takes to pull the engine out of my 72 240z? I'v never done it yet, but its developing a nasty oil leak on the front main seal, so I would like to freshen it up with some new gaskets and oil pump. I usually have school 5 days a week, but next 3 or more day vacation/weekend I'm wanting to do this. This engine is stock, dual carbs, all that good stuff, so it shouldn't be very difficult to do this would it? Only thing I'm worried about is exhaust. Where do I unhook it easiest? Thats the only think I hate about pulling engines is the damn exhaust, its such a pain! Thanks Also, wha…

Suddenly yesterday my engine started running much hotter than normal. So first thing I checked was all the cooling system stuff: coolant level (was low, couldn't tell how low), tubes, connections. No leaks. Had the system flushed and filled in the spring. I thought that maybe having filled the system in the spring, then not using the heater until this week caused my level to go down just enough to where it wasn't cooling properly. Turns out I was low by 3 quarts or so! Is this change in level normal for just operating the heater for the first after a coolant fill?

Hi guys I recently aquired a nice 240z. It is running an L28 F54 bottom end with E88 head and ZX valves. I've noticed on startup in the mornings it seems to burn at bit of blue smoke indicating some oil. I was wondering if the most likely cause would be valve stem seals or hopefully not oil rings. I haven't done a compression test yet but I do plan on doing it. The car had been sitting a couple of years with some minor use here and there. As I understand the valve stem seals are rubber arn't they? I've never really replaced/adjusted anything internally on an engine any deeper than the valve cover. However I'm eager to learn more about engine and plan on one day building a…

Hello all: It is time to get the short block of my L24 rebuilt, and I was wondering if any 240.org members had had good luck with any shops in the greater Sacramento (CA) area. Thanks in advance, Steve

I am not sure this tread will apply to you Uncle Sam Fanatics. Anyway, here in Europe Lancia came with one of the most unreal factory hot-road sedan. The 8.32 Thema is nothing more than a plain Sedan with a Ferrari V8 inside. I saw an ad the other day for a trashed Thema 8.32 and ... what if again ! So for you GTO replica owner, wouldn't you like to put a real Ferrari engine in your car? the engine was around 1500$ not cheap but it would have the real Ferrari badge on it. Performance wise it's kind of light at 215 hp, but that sound!!! To be honest it has not a good reputation (reliability, running cost) but it's still a lot nicer than a Chevy or Ford or Buick one. Don't…

I'm trying to figure out, why does the L28 have such higher compression then the L24's? I know its not entirely the head, and both engines have flattop pistons, so what gives it such high compression? Is it the stroke on the crank? Or is it the larger diameter of the cylinders? I'm wondering if it would be possible then to put a 2.8L crank into a 2.4l engine. If so, what rods will I use, or are they the same? I'm just wanting to get some higher compression in my 72 240z motor without actually switching blocks, I would like to slap an N42 head on there, but the compression in my stock engine would drop if I do that, so I'm seeing what all I could possibly do? Thanks

When I do my little rebuild/refresh on my 72 240z motor, L24 stock, I would like to put a better head on it, its got an E88 right now. I was wondering if an N42 would be my best choice? How much can they be bought for? How much for new seats since they'll probally need them. Will this give me better compression on my engine? Any ideas on power gains over my high milage stock E88? Thanks

Would an electronic distributor from an 82 280zx Turbo automatic trans car work for me on my 72 240z? I want to convert to an electronic setup, but dont know if this will work.
