Collapsed hydraulic lifter - advise, views and opinions wanted

Could you not squeeze the engine parts into your and Barry's Suitcase when you attend VOA Home coming, then drop it off at Arrow?

I just spent a ton of Money with Arrow getting motor parts and here is what I learned in the process that I believe will help you. The Stock "708" cam is machined cast steel.

THere are two other cams, one being cast with "a bit" more lift and duration, and a Billet Steel camshaft version. I bought the billet steel one. It is a work of art and I suspect will last a good long time. I have a bit heftier valve springs (not by much) but was assured by Todd that they would not affect the longevity of the lifters or cam. No pics of the cam prior to installing it though, sorry.

Thanks for this - cast vs forged I guess - do you have any more info?

LOL - no, it's my meccano set and only I'm allowed to play with it

What kind of info are you looking for?

What are these two option? Guess it's Arrow products and I should talk to them.

Madmax, my lifters shit to bed recently. I'm going to swap them out. Are you sticking with the '92-99 lifters or are you going with something else?

[95Viper]

Johnson Lifters are the ones you want to use.

Johnson Lifters are the ones you want to use.

Specifically which one and why use them? There are three that I know of produced by Johnson for Viper. (1.) Retro fit reduced travel (2.) Retro Fit short travel and (3.) SPT Performance custom version with stabilizer links. The current Mopar low-bleed lifters are produced in Mexico but available now.

EDIT: I called Johnson and spoke with the engineer that designed the Viper lifter. He recommends part#2313V10R for non-racing applications and it's designed for a 47 second bleed down test (using bleed down fluid). I believe the Mopar low-bleed lifter was designed for 7 seconds. The Johnson lifter is the one available through SPT. Johnson recommends using oil no greater weight than 10w/40 with these lifters.

Okey guys-n-dolls - the rebuild is well underway.

All the shit is cleaned up and broken bits accounted for.
New compcam cam in - new oil pump - new hydraulic lifters.
Timing chain cover back on and balance damper fitted.

Head install begins tomorrow - can't remember what torque settings I used last time with the cometic gasket and ARP studs.
Any ideas? The book says 90 ftlbs which I guess would be for bolts but I'm using nuts on studs. Would this make any difference?

[MADMAX]

At last, my rebuild project is complete and she's back on the road again - queue the shit weather - it's been raining for 48hrs solid.
I did manage to get an hour on the road Saturday and check everything feels and sounds correct and it's all seems good.
I'll run a few miles on mineral oil then change out for mobil 1.

Still puzzled though not knowing the true cause of why the cam and lifters had worn like they did.

Hope nobody else is suffering the same problem.

Ade.

Great to hear you got the car back together Ade

Look forward to getting out for a few more runs.........If it stops raining

I'm reading this post. I was planning on doing a engine rebuild on my own as a preventative measure for my gen 3. I have 61k on the clock. I wanted to know if you did the work yourself and how difficult was it really? I know it'll be time consuming but as far as how hard it was on your own?

I really don't want to pay a shop to do something I can do myself, but if there is too much margin for error with OEM parts and sizes I might have to.

[Fatboy 18]

"Madmax" has moved away from the Viper world now. So its not likely he will post here.

Stick a post up in the Gen 3 section, Im sure people will chime in.

If the car is still running correctly and not showing obvious signs of wear(blue smoke/burning oil), why rebuild? Unless you're going for big N/A power?

[Whozaka]

I'm still new to the viper world. So I wasnt sure what to expect. if these engines just fail randomly?

Do the basic maintenance, they will last forever.

For real? I've read many different things. Some say they will last forever as long as you drive them stock and do basic items. Others say you need to replace everything for longevity. I'm at 62k miles right now.

You make me so happy about that. My biggest worry is the engine failing over something I could have done work to myself to prevent it.
