Jeezz, can't believe I missed that thread!!

Just making making my orders and have a few silly questions....

The valve spring kits I see on LMR etc, say exhaust valve spring kit...... are they not the same on the intake side?? Don't I just need two sets of the same springs.??.. (16 springs a kit).

 

[ArizonaBOSS]

You want quantity (2) of these kits: M‑6513‑M50BR (32 springs total)

Thanks! Got them ordered as well as the timing chain kit, and already have my paws on the CJ oil pump. Going to be fun!

Just going over the last details before dropping the engine...... Should I get new keepers and spring retainers as well??

I assume thats 64 keepers and 32 retainers and they are sold individually from what I see at Tasca...

I reused mine, but it can't hurt you. Probably a good idea to order some keepers in case you lose one somewhere in the process (so long as it doesn't get lost IN the engine)

Did you use the OEM or ARP bolts for the following... I just noticed that they are one use only bolts...

And if you use the ARP bolts,,,,hex or 12 pts...???

1)N806183-S437 – Camshaft main cap bolts, 40 needed (10 for each camshaft being installed)
or ARP 156-1004

2)BR3Z-6279-A – Camshaft bolts, 12 needed (3 for each camshaft)
or ARP 256-1003

3)BR3Z-6A340-A – Crankshaft pulley bolt

Did not find the ARP bolt yet.


Maybe I should get a Cam shaft degree kit as well....

Dam, was going to take the engine out before vacations in Canada in two weeks, but looks like will be waiting a while...

 

[Mad Hatter]

Crap... if the engine is coming out..... might as well check out the bearings and rings etc.... Should I just use the Boss 302R head bolts or get the ARP ones... (long wait for those, and double the price)

I would use the ARP pieces, not a fan of torque to yield single use fasteners.

 

[Mad Hatter]

Do you guys think its a over doing things to change the main bearings and rings since I will have the engine out?? Calculated that I have about 70 to 80 hours on track and 50,000km overall. Part of me says yes and the other says leave i t alone!

 

[TMSBOSS]

Inspect and then decide, if you can.

 

[Mad Hatter]

I guess thats the way to go.... But to be ready to pop the heads off... will need $$$, things like rings, ARP head bolts etc.... My wallet is getting scared already!

 

[TMSBOSS]

Hear ya.

Compression test along with a scope in the plug holes could possibly show an issue. Not too invasive for the engine or wallet.

 

[ArizonaBOSS]

@Mad Hatter We have gone back to just using OEM bolts for the crank pulley. $3 each no big deal just buy a few and keep some spares on-hand.
For the cam cap bolts I did switch to the ARP hardware (although I had reused my original cap bolts once). The ARP PN for the cam cap kit is 156-1005

For the cam phaser bolts, I have re-used the stock stuff 2x now. I didn't know ARP made a kit.

 

[Mad Hatter]

Thanks, I got the 12pt ARP-156-1004 kit instead of the hex kit ARP-156-1005.

This.
If the engine has been well maintained (and I'm sure it has) a fresh oil gear and valve springs should put you in good shape.

 

[Mad Hatter]

Just getting the final planning to fit between the monthly races..... My mechanic wants new Roller Finger Followersetc..... I said not needed.... but then I saw @ArizonaBOSS pic

 

[ArizonaBOSS]

@Mad Hatter all of that stuff is what came out of the engine, aka stock hardware. I reused everything, except for the valvesprings and the intake cams. I just laid it out like that so I could remember where everything came from.
