Thought i should write som about the misery ive been through for the last couple of months.. It has been some really learning months for me and exhausting aswell. So im gonna share my experience.
Im gonna start from the begining....
In oktober last year my 1.8T (longitudal) sufferd a timingbelt crash. Wich ment that all of my exhaust valves were bent. So i decided to get a new head.. I have an ANB engine.. so i ordered an AEB head.. Why? because im stupid and cannot read.. So when i got the head i first realized that i had recieved the wrong head when i saw the BIG badass intake ports.. ??
But im a 20V I5 guy so i thought hmm ahh flow is nice.. and it was a cheap head asweell. So i swpped it in along with an AEB intake manifold and a South.. something gasket.
I wasnt really happy with the K03 so i decided to Buy an eBay K04 just to try and se.. And as if that wasn enough i ordered a tubular manifold from eBay aswell.. just to make sure i have some nice flow.. When all things where put together the car started and didnt run very nice.. it missfired and ran really bad. I used VAG-COM and found out that the O2 sensor had been damaged.. probably during the installation some how.. I changed the O2 sensor and the car ran okey but not very good.. Later I discovered that the FPR also had been damaged by me a was spraying gasoline into the engine wich is not good for anytyhing.. I emtied the engine on oil and changed the FPR and it was upp an running again.. The K04 turbo gave a nice pull and felt really nice..
But after like 2 days of testing a knocking sound appears in the engine.. My first thought was that one of the lifters must be damaged. But the knocking sounded more ditinct and hard puncing.
I used a stetoscope and litened to the head.. heard notting!! listened to the block.. and there it was.. klonk klonk klonk.. with a metallic sound..
Weeeell what do you do when you hear klonking sound from the bottom of the engine Time for Lift Out !
