Broke 3 rocker arms. have changed the rocker arms, fixed the timing. tried to start and hear a soft popping sound. where sould i go from here? take of the topp? valve number 3 from the front was hard to ajust.

Sounds like a bent valve you could pressure test each hole but sounds like the head is coming off

Good luck with the rest of the job. Carefully turn the engine over by hand to test for valve clearance problems. If the engine won't turn a complete revolution by hand something is out of time.

Don't worry, you're not the first DIY mechanic to break rocker arms. If you still don't feel confident take it to a reputable repair shop.

Thanks for the help! I will continue on with taking out the top, I have time but not all the know how in engine repair. Taking it to the mechanic is way to expensive here in Norway 100-200$ an hour in labor, and i payed about 3500$ for the car.

Use fresh engine oil and lube the cylinder walls the roll the end over and when piston 1 & 4 are top dead center cover pistons 2 & 3 with rags and start cleaning the tops with carb clean brass wirebrush and scotchbrite. When you are happy use compressed air to blow any debris away. Then reoil the rings and roll the end over again to bring up 2&3 but watch cylinders 1&4 the oil will leave a ring on the cylinder wall wipe up this ring it will contain debris. Then repeat of the other two holes.

Good luck
