    Posted: 14 Feb 2020 at 10:13am
Hi there. My problem is this: I have done a full engine generation (complete control replacement, crankshaft bearing replacement, cylinder head repair, valve alignment, valve stem seal replacement, ring replacement, ignition transformers replacement). The car got much stronger, but for some reason the fuel consumption increased by 3 liters (from 7.5 liters to 10.6 liters). The lambda probes and the air mass meter are good, catalyst is fine.
Please help me out what may be the reason for the high consumption.
Thanks.
