Any 88 Or 89 Mm Piston Alternatives For Stock L28 Crank And L28 Rod Combo?
Ring size is close to what I need. Maybe I can find some moly rings for a Chevy.
- Pay it forward!!!

L28 Rebuild? Swap? Leave Alone?
I'm on the side of "do it". I bought that Tom Monroe book, read it about 3 times then rebuilt my 1st car motor all by myself and it turned out perfect. One of the best feelings I've ever had, although there was a lot of anxiety and "while I'm this far why not do this...". I could have easily done a good job for under $1,000 but I bought a new exhaust and header and a few other "while I'm this far why not do this...". If you'll post some pictures you will get a lot more info/opinions. Cliff

'72 240Z Rebuild
I haven't seen anything that looks like a date code. It's an E31 that came with the tomato colored 240. Triple webers aluminum flywheel f54 bored thirty over with new dished itm pitons. He was following datsungarge.com to the letter. Needed money so now it's mine. Had to do something with it.

'72 240Z Rebuild
I used a scribe to scratch the outline of the HG. You can see it, barely. Do you think soda blasting the bare head would be okay? I'd like to clean the outside, not getting near the combustion chambers. Thanks Steve.

'72 240Z Rebuild
I figured that would be the answer to my question, thank you both. So that means the head has had the bigger valves for awhile. The intake seats do have a little magnetic pull though but nothing like the exhaust side. I guess beryllium bronze has enough tin in it to attract the magnet. Oh well, at least the steel seats are cheap but my machinist is gonna get sick of me quick. I've been smoothing all the sharp edges in the combustion chambers and I tried my hand at unshrouding the valves. Am I trashing an E31? I sure hope not.

71 240Z Chattanooga, Tn - Estate Sale
Judging by the furniture I thought for sure it was in pristine condition, I was wrong.

Wheels... Beating A Dead Horse
I was thinking you had red interior. I looked through your gallery this morning and saw that it is black. That above picture is very tricky to my eyes, it looks like a red headliner and that is all I could focus on. Didn't pay one bit of attention to the seat's head rest.

Another Coolant Leak
Blue had the best idea for cleaning valves to me, chuck them into a drill. Low speed with a Scotch Brite pad and some cheap WD-40 knock off. Shines up like new. I did a few last night. I'm working on a head that's been sitting under my bed for 3 years, they have a varnish like crud around the sealing edges. Agreed! very satisfying process.

Importance Of Heat Shields
I knew those were there for a reason. When I put my header on I had to trim around the middle runners to get it to fit, glad I did.

'72 240Z Rebuild
I decided to take apart my E31 before I give it to the machinest, trying to save him some time. Well there was a couple of surprises. It looks like someone has already ground the area around the valve guides and they are steel, checked with a magnet. The intake valve seats are brass and the exhaust are steel. It had the shorter Ford valve seals which I ruined when I removed them, I'll get a new set. I've got a Felpro beside the Viton for height comparison. Should I get steel intake seats or leave the brass? I'm not going to the racetrack and when I run it up it'll only be quick and short. The police know me and where I live with my orange 240, small town. Thanks for any advice, Cliff.

That's a beautiful car you have there. I really like that color combination, reminds me of a late 60s 911 my uncle had when I was a kid (younger).

Another Coolant Leak
Maybe snugging the head bolts up would help until you're ready for pulling the head off? When I tore down my 2.4 a couple of weeks ago I was amazed at the difference in effort to remove some of them.

Injector Leaking.
Funny thing about that is my Dad showed me that when I was a kid in the '70s. He was working in the yard and stirred up some yellow jackets that lived underground. They wore him out in about 30 seconds. A couple of hours later he got his revenge. That hole burned like JFKs Eternal Flame.

Radiator Drawings
Okay, I'll rephrase. If I can take some measurements for you let me know. I have the OE '72 radiator hanging on a nail in my garage. I've installed the larger 280 radiator in my 240. Fits great although it's 2" lower to the ground but still not as low as my front spoiler.

He should send him Tom Monroe's "How to Rebuild " book, that'd be funny.

The inner gerotor gear is larger for the turbo pump, creating more volume/flow. It's a good upgrade.

As much as you've done, I think you should drop the shaft. Not time to start jimmy rigging. When I did my 240 I had to drop the passengers side of the front sway bar. I loosened the drivers side bolts and zip-tied that end, put a small bottle jack on the passengers side and dropped it about a foot. But then again you could swap the wires and hear the thunder.

Injector Leaking.
That last picture looks a lot like a "method" for checking 6 future employees. Hey Rob you're making me jealous you know? I can barely hike up and down my stairs. I've always pulled the coil wire off when adjusting valves. Works as a good theft deterrent too at long term parking lots.

That's Schneider Cams stuff. Its the 270-80F I've never been down this path before so I thought I try and stay on the cheaper side. Time will tell.
