I have no data on oil flow from the pumps, so difficult to comment tbh. But just closing up the tolerances on the original oil pump works very well, but it’s an ‘in combination with’ kinda thing. It’s got the potential to be the same story as the diesel boxes having ‘bigger bearings’ in them...

The reason they let go is because the oil pressure on the f4r is absolutely dire. The cranks flex, centre main spins and goodnight vienna. There are many reasons for them to fail, which I’ve listed many times before. But as far as being a ticking time bomb, I’m afraid I disagree.

You can get a conversion kit to run the zf8. Lad at work has it so he can run the zf8 in his 135d

That’s what was measured from a genuine Grp n cam timing tool. The issue you’ll have with 421’s is that they’re going to be done to maximise lift and duration for the intended use. But only one way to find out, and that’s to try it.

7 degrees advance on the inlet cam and 4 degrees r****d on the exhaust cam.

If you know the specs of the cams, Ian will be able to tell you if it’ll work with the rest of the engine spec mate.

Knowing the f4r like I do, I don’t think any double valve springs are suitable for the standard hydraulic lifter setup mate, as the oil pressure up the top end is piss poor. However, if you are suffering from valve float, that’s not an oil pressure related issue, it’s a fitted length issue...

Message Ian and have a chat if you haven’t already mate 👍🏻

On my old mk2, the throttle body caused a lot of problems. It would start up and run from cold fine, let you blip the throttle with no issues. But once there was some heat in the engine, it wouldn’t work and remained shut not allowing the engine to start. In the end it turned out to be the...

No problem at all mate. Gotta be honest, as soon as I read your latest update and you mentioned the issues with the valves, I was on my way down the valve float route myself. Cams can be very temperamental as not every engine responds the same - so what works for the Evo boys, won’t...

I’ve spoken to him and after a brief description of what’s happening, he said immediately - valve float. Regardless of what valve springs you’re running, if they’re not installed to the correct fitted height, you lose spring poundage quite dramatically. I mentioned the lean, then straight to...

Let me contact a mate of mine and see if he’s happy to go through some stuff with you. He’s a very switched on fella when it comes to all this kinda thing. 👍🏻

Do you run the full vvt inlet on this?

Pretty sure that chrispy clio retained the a/c on his with itbs mate back in the day, so I can only think the a/c compressor would be close to the filter. I know the original lower inlet has a mounting point on it for the alternator/ac comp/engine mount, but it’s nothing that can’t be overcome.
