Just found out that the company rebuilt the engine is very dodgy , phones not valid , very bad reviews on the internet .
My mistake didnt check it before , just trusted in invoice . Another lesson....
The engine was fully reconditioned 9 months ago - 1k miles -by Auto Engines Uk
It had that common ticking noise though , but was pulling ok on test drive .
When driving home it started rattle more and more and finally gone with big oil leak.
