and also should i look for the engine code aj30 as it runs vvt or do you think that will complicate matters
i hopefully will be using the same block just trying to match all parts that might have been damaged

I have a full jag engine and I still stuck with the ford heads as they flow more than enough and mine revs to 8000rpm and has 700bhp with a massive power band with loads more to go, so didn't need any extra help from VVT smile

BTW the water runs different route through the jag engine so you would need a revamp of the water system to run jag heads.

It sounds like a man with big hammer inside my engine
I change the oil and filter using a ford filter and shell helix
Then two laps at snetterton behind the safety car and then it was time to go home u
Not even a flick of a oil pressure light probably will install a pressure gauge at same time

You should be able to rebuild your existing engine but the concern is why it failed so quickly especially as you say you have a track sump!
How long have you had the car & what's the oil level now ?

They don't fail at low mileage for no reason, I've seen this several times the past couple of years at a couple of track days when the oil level has shown still at or slightly above minimum. if you let the engine oil level run low even with the track sump, you will loose flow to the bearings in high speed corners. It must be kept at the top half of stick or as close to MAX as possible.

It happened to me at the Nurburgring. Never let it go below half way since and raced it dozen times and no problems.

Get the bottom end rebuilt by Jetstream and be on your way again.

The problem is actually the slower tight right hand corners especially if directly after a tight left hander. I will soon have a solution to the track sump problems wink

Great stuff Kev,

On my one it was a very fast left hander, brake from 140 to 90mph then turned hard right and as I powered away, pressure dropped and vibration started. Clatter clatter frown

Hi Kevin,

Dry sump next year then? Hope you had a great Xmas and see you up at Combe at the GWS?

Hi Dave
Very busy with family but good thanks & hope yours has been great, hopefully get to catch up at Coombe.

Wish it was dry sump but too many issues to resolve alone, can be done but the development time & cost have made it unviable so have redesigned the existing.

Happy Newyear

Cheers
Kevin

run an oil additive like slick 50 - it will save your engine if you loose oil pressure
