Hello, I have a 1.4TSI twincharged Golf Variant Model 2010 done 27,000 km. The timing chain tripped resulted in bent valves. I rebuild the engine by changing the valves, pistons (though they were okay), and the timing chain. However, immediately after rebuild, the Car started overfuelling. When I remove the dipstick, the oil smells petrol. There are also traces of petrol in the dark suit being emitted in the exhaust. Besides, the car fails to start at times but if I leave it for 10 minutes to an hour, it starts normally. But when it fails to start, I can press the accelerator while cranking and it starts. After the rebuild, I used the car for about a week and then the car started to show the red blinking Alladin's lamp and the check Engine. After that, we changed the oil and the problem was gone. That is the time we realized oil had mixed with petrol. Besides, the car is showing the following faults when scanned. 10 0 P000A "A" Camshaft Slow Response (Bank 1) Intermittent and the other one is Bank 1 intake too Rich (Cannot remember the exact code for this).
The compression is okay, Fuel pressure is also fine and I bought new spark plugs. What would be the problem? Kindly help me
