Define better. Less rolling mass is easier to get moving, but smaller rolling diameter means more engine rpm to achieve the same speed.

Well I got the fourteen inch studded ones for winter and ordered some "vintage" (tire guys are hilarious) fourteen inch white steel rims. Mr. Tire guy said that I needed to run low Pros and big rims "for better ride quality and comfort" lol. Do these guys get commission? He also tried to convince me that my studded tires were way to small and I should not run them.  :rofl:  I was thinking "hah, I can run what I want!". If she doesn't blow before June we will be at Canby.................................................... (now theirs a big IF if I ever saw one)

Drive a Datsun to Pasco in April first. See how you do with 80 miles before you drive 250.

Aaaah it'll be fine.......

Actually yeah I was planning to make a drive or two before. Also my summer tires will be a little bigger.

Looks like you figured out how to keep your truck from rolling away too.

 

Nice truck.

I wanted to go back and redo my oics, but something wasn't working right and it was giving me trouble, so now all the old oics are plopped in the middle of the thread. But I knew that if I did not do something to placate you oic hungry monsters it would be terrible. Blasted photo bucket.

When you don't have a handbrake or compression you have to get creative. :)

I had my 510 roll through the garage door at my parent's house when I blocked the wheel like that. I saw it running away and tried to stop it, and it ran over my arm in the process.

 

Those were the good ole' days.

When I go to re torque my head-bolts after the head gasket replacement do I take them out one at a time and then put them back? Or just check to make sure they are still at 59.5 ft lbs?

Loosen them one at a time, but no need to remove them. Then retorque the same one you just loosened.

 

Two tips: do the retorque cold and take the radiator cap off to relieve any cooling system pressure. If there is cooling system pressure when doing a retorque, you run the risk of sneaking coolant past the head gasket and into the cylinders. It's remote, but it has happened. Better safe than sorry.

Thanks, wilco. I should drive it a bit, get to temp, then wait till cool and retourque. Then do that again in 200 miles or so?

I have never been able to be sure that the tensioner is still compressed adequately by looking down in there past the blue tool with a flashlight. So your assertion that it is still tight makes me nervous. That you did not disassemble with it being at TDC makes me even more nervous. In your situation, I think I could easily screw something up and then have to go back in and take it all apart again. This situation just sounds dangerous to me.

 

I know that most people think the blue tool works well. I do not. That is to say, I have tried all kinds of things including the blue tool and, in each case, when it is all back together and the tool is removed, I can see the tensioner piston is not nearly tight against housing. (The shop manual calls for 0.00“ gap there. In other words, completely compressed.)

 

Having been in a somewhat similar situation, I found it was far better to set it to TDC, take off the cover, compress the tensioner with a tie wrap, and set everything back up in time and then button everything up. When you cut the tie wrap, you can see that you are at spec. Perfecto!

Well you were right..........


Are these an interefance engine?

I was driving along and it lost power and made a bad noise. Now I have no compression. :-( So I believe it met the same fate as my 4wds last engine. so my current plan is to buy the engine that just came into the wrecking yard (it has 150k on it) and then do a total rebuild on this one. So my current question is are these 85/86 Z24s non interfeirance engines?

I don't think they are.

Unless your mechanical timing was off by at least 60 degrees, you wouldn't run if it was, or your chain snapped, interference should not be a concern.

Picked up a wrecking yard engine for $300 that was "running rough" so I will be putting that on the stand over winter break and figuring it out. Then I will put it in this rig and take its engine all the way out and put new timing parts on it, then I may have a spare running engine which is something I wanted anyways.
