  3. What counter weight? I have the same problem with my '76. Thanks
  4. I'm putting my L28 back together after replacing the rings, bearings, valve stem seals, etc. The engine had two bad rod bearings which is why I pulled it apart. I had removed four of the cam towers to get my valve spring compressor into position. I kept track of where they went for reassembly. I've got the towers back on and the cam in place. I left the towers loose while I slipped the cam into position. I can tighten all the towers, except the back one (#5). If I tighten #5, the cam wont rotate. If I leave it loose and tighten the 4 others, the cam rotates smoothly. I played with feeler gauges and found that if I put a .04 feeler gauge under the #5 tower and tighten it, the cam will rotate freely. The thinnest tower shim I've found is .15. I really don't want to try and shave .04 off the other 4 towers. Ideas? Thoughts? Thanks
  5. Good points Carl. I saw a used crank, rods, pistons from an L28 on C-list. I'll take a look at that.
  6. I've been reading all the stuff I can find on interchanging 240/280 engine parts. I have a 1976 280Z with a N42 block and N42 head. It has a destroyed rod bearing (#5) which chewed up the crank journal. The top half of the rod bearing is gone and the bottom half is smashed paper thin. The car has an automatic and I wanted a 5-speed so I found a 240z engine and 5 speed, cheap. The 240Z motor is a P30 block and a E88 head. I did a compression check on it and one hole is at 35, the rest are decent. I'm in CA and 1976 is still a smog year so I need to retain the stock EFI, I believe. As I think I have figured out, assuming the 240Z crank, rods and pistons are good, I can put my N42 head on the P30 240Z block (new bearings and seals of course) and all should work? Thanks!
  7. For those in CA, not only are the reg fees high, DMV is looking to get back fees for a car that has not been registered. A car that had not been registered for 5 years would "fall off" the system. When you went to register it, you would start from scratch. Now they want all the back fees. I was looking at a project 240z, the price was fair, but the DMV back fees were $650!. That was a deal breaker. You can try and get the penalties waived, but it's up to the manager at each DMV. Make sure you ask about about current registration when you're looking to buy. You can go to DMV's website at www.dmv.ca.gov, go to the online services page and then the fee calculator page. With the VIN you can put in some basic information and find out what fees are due. It's well worth the time!
  8. If you can look down there, check the tensioner. If it's still in it's housing, you may be bale to push it back in to get your wedge back in there. If not, the front cover has to come off. Be careful when you take the oil pan bolts off so you don't tear the oil pan gasket. The timing cover uses the oil pan gasket a the bottom.
  9. I have one for the 240-Z. It mounts on the over rider guards. The chrome is great but it has a small bend in it where someone must have tapped something when it was on the car. It's not very easy to spot but it's there. I also have the rear with hardware, also in great shape. Let me know if you're interested..
  10. My son's '71 240-Z started making a noise that he describes as like a playing card in bicycle spokes. It's definitely speed relative as the noise tempo slows down as the car slows. He hears it in all gears and even when coasting in neutral. He says it's coming from under the console between the seats. I had him jack it up and turn the rear wheels manually, no noise. He noticed a lot oil residue under the car coming from the transmission area so I thought maybe it was low gear oil so he checked and it took a full quart!. He only had one quart so he put the drain plug back in, drove back to the parts store for another quart - noise was still there. When he got back home, put it back up on stands and took the fill plug out, the oil came gushing out! It didn't dribble out when he filled it the first time! He has tried coasting in neutral with the clutch in and out, same noise. He's heard it in gear (all of them - 4 speed) and it's always there. I thought maybe it's output shaft bearing? Front U-joint? Any ideas?
  11. The Dana cruise control for about $90 on ebay worked great in my '71 (similar one here http://cgi.ebay.com/ebaymotors/NEW-Cruise-control-after-market_W0QQcmdZViewItemQQhashZitem2304c461a5QQitemZ150403834277QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories). I used the magenets on the driveshaft and used a transmission mounting bolt for the sensor so I didn't drill any new holes. All the electronics are contained in the servo unit which I mounted on the passenger side fender inside the engine compartment. I ran the cable to the throttle linkage on the firewall and put the small control module on the center console. It works great and does a great job of holding the set speed. You can also "tap up" or "tap down" to increase or decrease the set speed by pressing buttons on the control module.
  12. Score! Northern Auto Parts has the ITM pistons and rings. Thanks 2 Fast 2 Z !!!
  13. Great input guys! I had totally forgotten about balance!. I have not replaced pistons in a looong time. I'll buy a complete set. The only set I've found is eBay. I did find the ITM website and they list a set, but Isent an email and so far, no response.
  14. I'll try Summit. I only need two because just two got chewed up on the edges. The other 4 are fine
  15. I'm trying to find 2 standard size pistons for my 240-Z motor. Nissan says there are none in the USA. Motorsport does not have them, Kragen can't get them, my local auto parts storen can't get them. Any ideas? Thanks
