It all depends on if some are full of oil still. Hydraulic lifters can be moved up and down unless they are packed with oil or blocked. Givem a good cleanout and test them again. Personally I would whack them all back in the engine. If they aren't noisy then leave em alone. If they are then replace the offenders.

Hydrolic lifters should be bled before you reintall them .

This is how you bleed them : Imerse them in in engine oil , get a wire that will fit in the hole , push the wire in the hole then try pumping the by hand until they become tight and no more tiny air bubbles come out . at all times you must keep the totaly in oil and in upright position .

Then install them in the engine start the car and they should be quiet after about 30 seconds .

When they are fully bled it should be imposible to push then down by hand .

thanks for the info, I'll go and try that first..... I got a quote for new ones and it amounts to a 1000 euro's which is approx 2000 aus$...then I'll rather convert to Tomei solids.....

Tomei Solids are designed for cams of a smaller overall rolling diameter.. the Stock diameter is 32mm and the Tomei Solids are designed for a 30mm diameter camshaft, so that you don't need to reshim for the installation of the higher lift PROCAM... Look again dude.. if you change to solid lifters, you might want to consider the base diameter of your camshaft... Tolerances here are not good for 1mm of pliable crap to runa round!!!

I meant the complete tomei package (lifters,shims,springs and cams) that should cover all tolerances; shouldn't it?

In general terms Tomei provide just about everything in their line up, you just ahve to know what to pick.. You generally don't need the solid lifters until you are long way into the Lift side of things. If you are prepared for this then go for it..

well since I most likely have to replace them anyway and the tomei stuff will only cost me a few hundred bucks more, I'd rather go for the tomei stuff.(building the complete block for high boost anyway(pistons,rods, new bearings,upgraded oil/water pump etc) and with the tomei stuff it will also benefit from higher rpm limit and more lift)

you were right about the cam base circle, tomei lists stock as 32mm and the solid conversion is 29mm.....

anybody around here ever done this mod?

thanks.....

I haven't as yet, but will be ina few months, I am planning on going for the 260deg 10.85mm lift PROCAM along with the associated guff..

ok I'm interested in how it goes, also just bought an rb26 head for cheap, complete, that's also an alternative to convert to solid and up the rpm lilmit to 8200.........

      The final part arrived today to un-clampify and simplify the intake Who would have though a 1/2" hose stainless bulkhead fitting designed for below waterline bilge pumps would be what I needed Test fit on a 3" offcut I had laying around to see if it would work, and it worked a treat All going well the intake will be on its "final version" tomorrow

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.
