j4 van

Been a bit quiet lately due to being very busy.
After the mission to Oxford with Jon to collect the LDV V8 the J4 decided it was ill :I
Turned out the head gasket was blown on the middle two cylinders and no.4 exhaust valve was receding badly :(
So some serious surgery was on the cards :p

Slight modification was needed for Weber clearance, one stainless airbox (just don,t tell Harvey) :D

No SU unfortunately :( as the whole set up was dynoed in with the Weber, i didn,t want to upset things and start from scratch.
certainly get a very distinctive noise with the DCOE [^]

Against the V8 John [?][:0] just wait until i,ve added the blower [}:)]:D

Yes, but auto,s are quicker as you don,t waste time with gearchanges ;)
But i am prepared to give it a go anyway :D

Due to the extra heat generated by the more powerful engine, yet another bike radiator is sacrificed for the cause :p

I can think of several possible reasons.
1. don,t know the compression ratio, but its high, so 95 octane just isn,t cutting it.
2. i have been very cautious with it and lugging it rather than revving it.
3. i had the inlet manifold off, so may have had an air leak
4.its been a little hot as i can,t get the original fan on (yet[}:)])
5. i changed the points to electronic, so may have advanced the timing a tad.
6. it was already on the way out
7. i am very unlucky

Its probably a combination of some of these. I will have the new piston tomorrow so its on the mend :p
I shall be very careful with fuel from now on, perhaps some hydrogen hydrazine and propylene oxide :D
