Security,

How did the new lifter feel? Were you able to push it in and out?

I have roughly half of a set of 24 lifters that are able to squeeze in and out freely, others some are simply solid and a few are able to move slightly.

My old man said his ol HQ hydraulic lifters were solid and that you shouldn't be able to squeeze them in and out.

dont muck around with trying to fix them. if you inspect them all carefully you'll be able to see which ones are stuffed, if not dont worry about replacing them. i'll post pics tomorrow on what the stuffed one on mine looked like.

You said you blew them out? Maybe pumped air in to them?

I have a set of lifters soaking in diesel and appears to have really pulled quite a bit of crap out of them, the little hole on the top and side I can see a little stream of black crud.

One of the 24 lifters felt as if it was a little stuck so it will be interesting if it fix's it or not.

I'll give the kero a go.

I had thought about heading down to bunnings and picking up some toluene for the clean.

Yes Toluene is pretty damn nasty... :spank:

I'll stick with the diesel and kero.

I've never had any dealings with lifters before.

How are they supposed to feel? I'm assuming they are supposed to pump in and out easily, I have a 8 that are nice and free where as some of the other move a little and some are completely stuck.

still curious if this is the best way to clean the lifters out, im thinking i should start soaking the set from the spare head i have at home, so that they are useable when the motor is together.

also curious on hoy the lifters should feel when not under pressure.. should they be stiff or move freely?

You can clean them with kero if you like but you must bleed them if you don't they may not bleed themselves.

The best way to bleed them, submerge them in oil upright, get a thin strong wire put it in the whole and press it down then pump the lifter with your hand ( while holding the wire pressed) until all the little bubbles go. When the lifter is bled it will be very hard, you wont be able to push it down after you take the wire out.

Thanks for that :spank:

anychance you can dumb it down a little more?

upright being cam lobe side up?

whole = oil feed hole in the side of the lifter?

cheers

Thanks for that :)

Yes, the way its in the cyl head, thats upright, i never plyed around with rb25 lifters but usully the whole is on the top of the lifter( Sr20 are like that so i asume rb25's will be the same )

You should also measure the lifters for wear/ clearances, when you install them start the engine and run it for a few minutes without load, if they are not quiet after that they more than likely need replacing.

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
