Did you have to cut out that area in the tank where the cradle sits inside of?

or atleast remove the plastic filter on the outside of that area so fuel flows in quicker?

I've noticed both the Bosch 040 and Walbro sometimes struggle in high revs, I'm sure it's just more dirty in my tank, but while using my fuel pump to empty my tank for cleaning, I noticed both pumps can empty that area a tad quicker than it seems to refill when the plastic basket is on the outside ?

What did you do after that?

With the bosch and a heavily modified cradle I can get it about 5 - 10 mm away from the bottom of the tank.

Did you raise the height that the pump sits at?

I really don't want to have to clean my tank again but the sock keeps getting clogged. Hoping that if I use this Walbro pump and raise it up higher that I won't have the issue anymore.

I had a 040 in mine. It ran fine, but it was loud. I got mine down to about 10mm off the bottom of the tank. I switched to a walbro because the noise was driving me crazy.

I dont know if it made any change, but I pulled the plastic baffle out of mine when I switched to the walbro.

I put a walbro in mine about 5 years ago, never had a problem with it... except that I get fuel surge on a particular corner when I get below half a tank.

I've since added a surge tank and an external pump in the boot.

      Have you put an aftermarket oil pressure gauge on and verified your oil pressure?   Noise being on the block, on exhaust side, how high up the block does it seem to be? It could be the VCT system getting cranky, especially if it's mainly at idle, and when warm, as that'll be your lowest point for oil pressure. Could be showing that oil passages / VCT solenoid are blocking.

      Well, hydraulic lifters will get noisy if they are dirty/fouled in some way, and exactly how that manifests will depend on exactly what schmutz is where. There is a procedure on here somewhere for dismantling and soaking/cleaning them. Replacing them with new is about 50% of the work and about 5% of the money!

      Thanks for the reply @GTSBoy this is is a hydraulic lifter engine. Yea right i did not realise the lifters were supposed to be compressible while installed. I could push them down but i had to lean almost my while body weight on them.  I have never heard of a lifter/ lifters ticking only at hot idle and getting worse the hotter it gets. I have owned a few jdm cars with noisy lifters. This noise is slightly more subtle, it is more of a sharp gentle metalic tic than the solid and more loud tapping I've heard on lifters. I have used a metal rod, alloy tube, hose and stethoscope and could not find the source of the tick. But it appears to be loudest on the actual engine block behind the exhaust cam gear and next to the oil filter. I had mate (40 year old mechanic) go over it with me and he couldn't find it either..  Could it be a cam seal issue of some sort?  Cheers

      This seems problematic and unlikely at the same time. Vanilla RB2Xs have hydraulic lifters. They do have "zero" clearance, but only when running with oil pressure inside them. When not running, you should be able to compress them and obtain heaps of clearance. RB26s and Neos have solid lifters. They should have ~0.3mm and ~0.5mm on the inlet and exhaust respectively. If they have zero clearance then bad things are happening. With nothing else being wrong, it would mean that the valves would be held slightly (ever so slightly) open when they are supposed to be closed and it should have all sorts of problems when running, caused by leakage in/out through the valves. Or, zero clearance can indicate severe valve seat recession. None of it is good. Have you used a piece of hose as a stethoscope to try to localise the noise?
