200 miles turbo then...

[Yoof]

Was plug 1 tight when you took it out?

[Etches]

Yeah all were really tight. Was a mint runner before turbo went down as I went by something andy said yonks ago about engines having to be running well before the conversion.

Compression check next.

Can you explain this:

"Thing is my AFR was reading 10 whenever on 0.2-0.4 boost as my 6psi switch actually needed getting up there. Engine temps were always cool too. "

[AlexG40]

Could this be bore wash?

[Yoof]

Soon tell by dropping the oil- if there's enough fuel in it, should light fairly easily, and stink of fuel.

Sounds like something spesh is happeneing with your 6psi switch...

[Etches]

My switch was intiating full fueling early at around 0.3bar . What I was trying to say was that the engine temp, oil pressure etc etc was looking good.

[Yoof]

So about 4.3psi compared to 6psi. That on it's own wouldn't cause a massive overfueling issue, I suspect it's combined with another problem, especially if you're saying it's very rich on cruise (part throttle)?

Compression check (wet and dry) then go from there.

[Etches]

Right today I've done some snooping around

Number 1 cylinder





234 looked good on the bore scope.

Then proceeded with a dry compression check

6 9 8 10

I will do the wet check tomorrow. Looks like cylinder 1 has melted

[Yoof]

Fuel pump, injectors and filter/lines all good?

[Etches]

Injectors were cleaned before I got em. Fuel pumps always been decent and the afm always read pretty rich. Looks like carbon deposits but no. 1 pressures not good . What sort of pressure am
I looking for Pete?
