Hi guys
Can I savely re use the conrod bolts and bolts that is used on the main end bearing caps of the crank?
Please note I want to rev the engine to 8000rpm without worries about the bolts letting go because I should have actually replaced them.
I have had twho head bolts crack on me in the past without reason because they were torqued to correct settings.
I don't want the same thing happing to the conrod or any of those bolts.
Any advice appreciated.

cheap insurance, new Nissan rod bolts are good work..

Just think if you have had 30 year old head bolts crack, why would you even consider reusing rod bolts.

Do it once and do it right.

Thought so. What about the following:
Flywheel bolts.
I am going to put in a different camshaft. What must I do about the cam followers. New ones from Nissan is a killer.

Whoever grinds your camshaft should be able to re-face the lifters as well.

Is it acceptable? How much is removed from it when they re-face it.

great, make me feel bad for re using the main cap bolts, rod bolts and flywheel bolts will ya

It only takes a minimul lick, with a reground cam aswell it will change your rocker geometry. but since you head has probly be'n machined atleast once in its life it porbly correct it some?

Who ever heard of head bolts cracking? Let alone when "torqued to correct settings".


Head Bolts are not part of a rebuild, except on TTY designs, of which Datsun engines are not TTY designs.

New rod bolts are not part of a rebuild either, but for 8000 RPM i recommend the ARP bolts. Although new Nissan rod bolts are good too.

Main bearing bolts should be reused. Flywheels bolts too. No reason to replace these.

Torque to Nissan's specifications.

Rebuild will use a new cam, so you must use new lifters. Or they can be refaced for a performance rebuild.

Some more questions:
The engine blew head gasket once before due to a cracked head bolt. That is why I lost my trust in reusing head bolts.
They did give the head a slight skim when this happened.
I am going to run a 276 spec cam like the one on the tighe website. So you guys say it is fine to re-use the lifters just get it re-faced? The cam will be a stock A12 cam getting reprofiled. Can I then just send the lifters with and ask the guy to re-face them as well?
I have another A12GX spare engine which lifters I can use if the current ones are pitted or damaged which I doubt because the engine in the car has 150 000 genuine km on it.

Who used ARP rod bolts on their A series engines? There are currently two of us (Me and racetech) who are looking for info of which one's to buy and how to install. Clive said it is a V8 engine's rod bolts and there is people saying they must be centre grind to make them sit centre in the rod bolt holes as they are slightly thinner than genuine Datsun rod bolts. Any info here?
Another question. Is there a difference between the A12 rod bolt and A14/15 rod bolts? If the ARP are thinner, maybe they will sit better in the A12 rod bolt hole if the A12 uses thinner bolts.
Any info appreciated.
