timing chain and oil pump genIII

[camaro2you]

How good is the slp oil pump and timing chain kit? Ill be doing my k member and a-arms soon along with my oil pan gasket so I figure with 116k on the clock i should do those items. Thanks in advance.

[Saitin]

well I have a stock ls1 oil pump and chain with less then 5k miles on them if you are interested int hem.

[JSPERFORMANCE]

The SLP kit is very good stuff. By the way if you are going to go as far as changing the chain and pump why not do the cam as well?

[JerzLT1]

Josh is like that little devil sitting on your shoulder... lol

[JSPERFORMANCE]

Yeah and I shot the angel that sat on the other one!!!!

[LTb1ow]

Thats a whole new can of worms, at 116k the springs will def need to be replaced, valve seals etc etc....

But you get to play with magnet sticks! lol....

[JSPERFORMANCE]

These are all the usual things that get replaced when the cam is changed out for one with more lift and duration anyways. I am not sure what "can of worms" and "magnet sticks" you are talking about.

[LTb1ow]

If you don't wanna pull the heads on an LSX, you use the pen magnets to hold up the lifters, or I guess there may be some fancy tool for it... And can of worms is when you start on a simple project and then overload yourself and it never gets finished...

Fancy tool, pretty slick.

[JSPERFORMANCE]

I assume you are speaking from experience? Because I have never had to do it that way. And if a cam swap is overwhelming then dont bother with the timing chain and pump.

[LTb1ow]

I dunno?

On my engine, you just pull the lifters out, I was just reading up on LS1 cam swaps, and thats what I found....

[camaro2you]

Would it not be needed to change out the lifters to throw a cam in? Since the heads need to be removed to change them out then you get into the game of might as well yank the motor and put in new bearings and bolts......

[JSPERFORMANCE]

Shownomercy - please do not give tech advice on a subject you have no first hand knowledge in. Reading on the internet does not make you an expert and may cause someone to get confused when you give incomplete information.

Camaro 2 you - the lifters do not NEED to be replaced with most mild aftermarket grinds, but you are correct in thinking the "might as well" direction. In your case a simple cam and spring swap is not all that difficult since you will already have the pump and chain off.

[camaro2you]

What cam and spring selection do you recommend to give me a little power gain and a nice little thump?

[JSPERFORMANCE]

Your best bet is to talk to your parts supplier if you want a reccomendation. If you would like us to do the job give me a call and we can talk.

[KirkEvil]

I think SLP stuff is just overpriced for what you get. You would not need the double roller timing chain if you are staying stock or mild cam. An LS2 chain is enough and 1/4 the price.

Josh, when you are doing a cam swap without pulling the heads, do you just remove the rockers, rods then spin it over to push the lifters up. How safe is it to assume the lifters will get stuck there while pulling and installing the cam? Thanks.

I refuse to help with this Cody if John is there doing annoying odd things haha!

JW :D

[JSPERFORMANCE]

In most cases in engines under 80000 miles the lifters will stay put. We use the dowels most of the time just in case they dont.

[NastyEllEssWon]

dowels ftw

[KirkEvil]

So, the lifter tool that SNM posted is actually the same as using dowels

[NJ Torque]

I didnt do lifters on my cam... now I have lifter float... not making nearly as much power as I should.

[KirkEvil]

Anyway, camaro2you, why are you looking at just an oil pump and timing chain?

[BarneyMobile]

This is the first time I've ever heard of Lifter Float:-?

[NJ Torque]

This is the first time I've ever heard of Lifter Float:-?

Thats what Matt at TTP explained to me... Go figure, right...

[BarneyMobile]

maybe he meant valve float?

[KirkEvil]

lifter float as in the internals of the lifter are remaining collapsed at high rpm, or do you need longer pushrods? Im with BM on valve float, what springs are you running?

[NJ Torque]

Patriot doublt gold springs...

I was assured that replacing the lifters will solve the issue or ttp matt would eat the job if it didnt..

[KirkEvil]

Yeah those springs should support whatever you throw at it. Im guessing that you are running a custom TTP cam, do you have an idea of the specs? Or better yet, the cam lobes?

[NJ Torque]

XE-R lobes, 236/240 110.5 LSA

[BarneyMobile]

are you still using the stock rockers?

[KirkEvil]

Big cam, but I wouldnt expect you to have a problem with the XE-R lobes. Yes, they are aggressive, but I have never come across a case of someone with lifter float. I would think the LSL or XFI lobes might cause it. Usually a lifter decides to take a complete dump before a consistent resonance motion.

[NJ Torque]

Rockers, yes.


The car runs off of power @ 5600...

Yeah, I havent heard of it either...

So what do I do... replace the lifters? Hell... I might as well do heads while I'm there...

[KirkEvil]

Is it a gradual or sharp decline of power? Stock heads were not designed to handle the 6400 you probably want to rev to. Also, what intake are you running? I cant remember if you bought/sold an ls6 on here.

Thats another thing I was told about... the air getting turbulent in the heads.

Its basicly static from 4000-5600, no gain...

I have a ported fast 90 and 90 mm tb, the ls6 is what I pulled off the car.

Unfortunately I had a lifter go bad and I had to pull the heads just to replace them...it is not fun, but you can do it yourself. Aftermarket heads would be worth doing if you do pull them considering the price of gaskets, bolts, fluids, and headache.

[camaro2you]

Money wise while im down there just as an insurance to things so i can try and make this motor last till im done my 86 and can afford to build a 408.

[camaro2you]

Well this started out as oil pan gasket and is now turning into my 408 build I always wanted. Just picked up a 6.0 iron block over the weekend for $200....

[Saitin]

lol there is that might as well factor.
What is it a LQ4 or 9?

[camaro2you]

Not sure, i have to look into the number more all I know now is that its a 02-04 block.

[KirkEvil]

iron block = lq9 right? I think the lq4 block is aluminum

[camaro2you]

Both lq4 and lq9 are iron truck motors.

what company makes lifters that would be the best one to replace your stock ones with?

[S.J.SLEEPER]

CAMARO2YOU..... while everyone else went off subject. an gm pump is suffecient. but you can go with a melling oil pump and compcams double roller chain & gear, same parts as slp just cheaper bought seperatly. as for swapping cam,& springs, the "might as well" clause kind of does get implied. you are already that far. just stick a mild cam and springs in like a hot cam swap or 525-570 lift cam in it. will give decent power gain & won't be too harsh on your stock lifters. more aggressive than that, really not worth doing unless your gonna trougha set of afr's or tfs heads on it.
good luck with your project!

p.s. taking the valve covers,rockers & pushords out rotate crank
180* & lifters will stay retained in lifter cups. using dowels always a good precautionary measure. and change the pushrods to hardened chromely "might as well" since your already there !!!

[S.J.SLEEPER]

use ls7 lifters from gm

[LTb1ow]

LS7 caddy racing ones would be even better. :)

Thanks for the advice, ill probably go that route on the ls1 from the car before I put it in the s10.
