Sybele motormanagement Challenger 6

[alanius]

Hello,

Does anyone has got some expierence with the motormanagement from 'Sybele', challenger 6.
Is at this moment on a 4.0V8.

Engine was rebuild by turner not long before I bought it, inside still looks like new.
But when the engine runs it makes a knocking noice, first thought was bad hydraulic lifters. We replaced them this weekend, the old ones where still good (almost no signs of wear) but we've putted some new ones in.
We started the engine and still makes a knocking noice and doesn't sound like a V8.

So guess the timing - injection isn't good or does anyone has some other tips to check?

Thanks!
Regards
Alain

You say it doesn't sound like a V8 - is it misfiring?

Can you measure the temperature of each exhaust outlet to see which cylinders are not firing?
