I have a 1.8, and it runs like a bus motor, its a EC 1.8. i can be driving and it will be a 914 for a few seconds and then back to a bus...
so, i did a compression test 4= 80-60 3= 100 2= 120 1 = 100 and my plug on no. 4 is black. new plugs. what could be going on? the valves are not adjusted. and also, i feel like its timed right. but, then you drive it.... and it just not timed right... what could be going on with No. 4? and why would No.2 be higher? because its the opposite side? compensate? im a lone 914'er... and Vdubber... you guys are the only people to ask!

it could be that your motor is just shot...
but that is the bad news its worth doing a valve adjustment and maybe leak down to know buy a haynes manual and its relatively easy with a jack and jack stands..... or go to pelican and print a how to article at a minimum. |
