Hi folks. I had an exchange engine (1.9ltr DG petrol water cooled) fitted about a year before unleaded was taken off the market. It ran like a sack of crap on lead substitute.

The guys at Meon Valley Motorhomes where i purchased the van and who arranged the engine swap suggested fitting a Broquet

This was allow me to run the van on unleaded fuel and i have have done so ever since.

I am fitting new fuel hose in the engine bay and just wondered if i really do need this broquet as it adds a lot of fuel hose to the system but obviously as my engine is designed to run on leaded fuel i didn't want to remove it and cause problems to running.

Any expert advice gratefully received. Cheers

Before leaded was taken off the market that should say.

Hi mate,

designed to run on leaded?? You sure???

My 1978 VW derby was unleaded heads....and I have three T25s which on the 1.9 dg engine ran beautifully on unleaded....and the 2.1 DJ requires super-unleaded I was told. However, can be timed to run unleaded.

oh sorry - you asked for expert advice....mine certainly ain't that! Its more like "experience"

Good luck

All t25's where designed to run on unleaded even Aircooled ones and a Broquet won't make any difference if it wasn't.

Thanks that sounds very positive. Having said that the people the exchange unit was purchased from said it was to run on leaded?

Only if they fitted the wrong valve seats, or they don't know what they are talking about. This is VW's guidance on the subject.

That Broquet won't make any difference at all.

Cheers if it was the original engine this would be a doddle but it's an exchange but it should be the same spec as you say. ? oh well i'll take out out of the loop and see how it goes thanks again for the advice.

The exchange engine, depending on the degree of 'overhall' is unlikely to have had the valve seats replaced anyway (they tend to be re-cut if they need work). Bad cracks between the valves would require new heads (small cracks are often acceptable) If the seats were replaced they would have almost definitely been the 'harder' type anyway, as replacement parts are nearly always the latest available.
Besides..even the earliest engines were designed to run on unleaded so replacement parts for those engines wouldn't be earlier spec as they were ALL unleaded compatible.
I think you are worrying about nothing here.
You'll be fine.

Thanks again x
