Hey guys, I have my engine sitting on the floor in the garage, and I have not rebuilt an engine before so I would like a tutorial to help me with the process. I would take it to a mechanic but i want to experience it myself. I have been lookin around and haven't found a lot of tutorials on this. Does anybody have some good links to engine rebuild tutorials for the the 2.4L? Thanks Frankie

Here's my situation, my daily driver has a smog problem and won't pass smog so it's time for it to go. I have about a month left on my tags. I'm going to pull my 73 240 out ( been collecting parts for it to do a total resto) and put it on the road. I have to get hold of a short block to get it running so I figure I'll get a 280 out of the junkyard. I have a fresh E-88 ready to go on. I will do gaskets and seals, timing gear set, oil pump on it. Do I use a 280 timing gear set ? Do I use the 280 timing cover ? Will a 240 distributor work with a 280 timing cover and oil pump. Thanks

i recently tried to start my 73 Z for the first time in ten years and some weird metal scratching sounds were coming from the head. i removed the valve cover and noticed the back half of the cam wasnt getting oil. The base of the back spray bar was bent and oil would leak out there instead of being sprayed on the cam. Furthermore, the short spray bar in the very back was loose and almost failing out (as seen in link) http://www.classiczcars.com/photopost/data/500/medium/IMG_6174.JPG i have been searching the forum for a long time now and found tourniqet had the same problem but didnt find any posts that explicitly had an answer so, lets settle this topic once and for a…

I have a quick question regarding a regrind cam... I currently have a 240z with a stock l28, that has su carbs, headers and exhaust...would i benefit from a cam swap that much? Let say a 460 lift with 280 duration or something around there? Also what can i expect to pay for all the parts for a a swap? I really don't want to go through all the trouble and be disappointed with the results.

Well I have decided that since I already ordred my poly mustache bar bushings, I may as well install them. I know I need to leave my stock housings in the bar ends, but I need to know exactly how to remove the rubber from inside the housing. My clever use of the search button has produced a trick that people are burning the bushing out of the collar. Also described as heating it up and then forcing the rubber out. Can somebody elaborate on this before I take my torch and just melt the darn thing out!

My car is running lean mid-upper range. I picked up a clear fuel filter to see if there was good flow. Well if i crack the throttle the filter runs dry and it leans out. Assuming pump is failing it is a mechanical and it is old how old who knows. If i pinch the feed line from tank for a few seconds the pump builds pressure and when i release the filter fills half way. Sound like a bad pump or maybe clogged pickup? doubt pickup as the gas is clean as can be and this just happened in the last few days.

synapse for me... I just got the MSA battery tray mount kit. The car is a '73 240Z and the battery is an Optima Red Top. The problem of course is that the Red Top is not as tall as the original battery. I suspect the solution is to put something under the battery tray to boost it so that I can engage the bolt at the back and secure the battery properly. What have you guys used? Something plastic would be great as it wouldn't rot under there. It looks like 3/4" to an inch that it needs to be lifted. I know someone has dealt with this before...

While not new to cars buy any means i am new to the 240z. Picked up a fine example. Runs a little rough but still drives pretty good. My carbs are out of sync i can tell. REal rich smell and fumes coming from pipe. Sometimes even black. I am coming from the rx world and a rotary guru and am excellent with other makes and models. I worked at ford for 12 years as a mechanic. Its just been so long since i have monkeyed with side draft etc etc. I got them going pretty good lock nuts underneith 3 turns out idle set via two screws at 850. runs pretty good. Backfires threw carb if i stab it over 1/2 or 3/4 Guesiing timing is off or i am running lean up top. any help would be gre…

For a 1978 280z? Apparently the mechanic wants to charge me $110.00 :ogre: for all new spark plugs and labor. Does that sound steep or is that a fair price for the spark plugs required plus labor? I know I should probably just do it myself but lets just say that's not an option at this point. -Eli
