You’ll only need solid lifters if you start chasing big n/a horsepower tbh mate. I’m building one currently for one of my mates and that’s going on solids. Dry sump and 50mm itbs in the pursuit of numbers!
There’s a thread I started on here somewhere.
Ah right ok, well it’s not monstrous mileage tbf mate. I’ve had these lifters apart to make a dummy for converting an engine to solid lifters, and I can see how one could fail and stick.
Right ok. Well you’ve either got a failed/stuck tapper/tappets, one of the collets hasn’t swayed correctly, or as @bloke says one of the followers isn’t sat correctly. All my opinion, and I can’t listen to the sound files you’ve put on for whatever reason, so I can only guess at best.
So how have you checked the cam timing but not the crank timing? Did you not put the locking pin in the crank when you checked the cam timing?
What poundage rate are the uprated springs? Did you fit them at the correct fitted height?
Recaro Pole Positions are THE most comfortable bucket seat I’ve ever sat in mate. Did the journey over to the Nurburgring in mine loads of times and always arrived at both ends of the journey feeling fine.
Have you googled it to see if there’s any common issues?
I had a problem with my K4 Karcher. One quick google and £14 later it was fixed and back in use again.
I’m pretty sure that’s the main one for the ecu, so you need to be checking each one to make sure it’s connected. Volt drop is a good way to test them individually at the ecu plug. You’re looking for around 0.01-0.03.
Don’t resistance test them with the ecu connected - you’ll not make the ecu...
The pump and coil pack receive 12v as it’s switched by the earth.
Have you checked all the ecu earth points on the gearbox etc?
If it doesn’t get an earth it will do nothing.
So the Quaife is what’s known as a automatic torque biasing differential, so it sends drive to the wheel that’s spinning, but it never fully locks giving 100% drive. A gripper is a plate diff. This means the amount of lock up the diff gives can be setup according to the desired usage. However...
Well assuming the jb1 gearbox runs the same size diff as a jb3/jc5, you’ve got a few options. I can supply and fit a Quaife or a gripper. Unfortunately I don’t know if they share the same sized diff.
Whereabouts in the world are you mate?
