Hi guys,
Been fiddling with the series all day about the fuel consumption. Vehicle is a 2.25D 109 s3. Before the engine rebuild, it could go 400+ KM on a full tank of diesel(underseat tank, 45liters). After the engine rebuild, it could only get 300km tops.
For the rebuild, the pistons were put back to original sizing with sleeve liners. The crank and cam shaft had new bearings. Injectors and injector pump were all overhualed by professionals. Timing chain and gears were new. So pretty much nothing has changed expect the reduce in piston sizing.
Engine starts and runs well, but seems to have abit less power than before (just a feeling). Engine was rebuilt because the previous engine had the precombution chamber punch a hole into the block, so i had to get another 2.25D to rebuild , and replace the existing one.
Not much smoke on the exhaust, some black smoke on acceleration. All in all, pretty good for a 2.25D, except that it feels underpowered compared to other 2.25Ds i have driven, and the fuel consumption is high.
I have a feeling the underpoweredness and fuel consumption is closely related. The injector pump might be one tooth out, but i have followed the rover workshop manual word for word, so am not sure if this is the case.
Appreciate any advise! Thanks!
