Donnington Track Fun, Until Engine Died - Help Appreciated!

To save yourself working under assumptions. I'd still check the timing (confirm if valves are bent) for process of elimination.

Unless the garage already checked that before directing towards fueling components?

If you don't have a crank locking pin. Remove cyl 1 (gearbox end) sparkplug and rest a screwdriver on the pistons crown. Manually wrench the crank until it's at TDC. Then remove the rubber cam caps. Inspect the cams. You should see both cam timing tool slots inline with each other. Smaller crescent towards the bottom.
If this is what you see. The timing is not your concern.

If it isn't the above.
Don't see it often, but my old 182 had starting/spluttering issues. Ended up being a faulty throttlebody.
Doing a quick swap would confirm if it's this.

Check everything tbh, I've not seen a bent valve with compression, bent valves for me have always = no compression however checking cam timing should be very high up on the list of things to do.

So reviving this thread after a bit of time - usual life & work getting in the way….

Took it to my mates garage and it turned out the ECU was fried - managed to get a new (second hand) ECU and virginise it from the old one. This meant the car would actually start and show codes. Weird one with the ECU - anyone else experienced this??

Although it was still running like a bag of spanners and doing the same thing - idling really rough and sounds overly ‘inductiony’ when revving & then cutting out if you don’t rev it….

The garage pointed me to fuel pump & injector issues, so this afternoon I’ve fitted 4 x new injectors, a new fuel pump, new HT leads & a new coil pack. It’s already had 4 x new spark plugs as well.

And guess what - still the same…

I’ve compression tested it in the past as previously mentioned and got 4 x around 100 psi, so all low but all consistent

I’m very much now thinking it’s a bad engine and it’s engine rebuild time or new engine?!!

Any thoughts anyone - anything else I can do or check to diagnose?

Also as a side point - there’s this black sh*t on the floor of the garage from the exhaust which isn’t looking great….
