• I think my friend may have timed his engine wrong and bent a few valves. This is what we are looking at. He is in Toronto so I can't really have a look at it myself
  
  What are the chances that the head will need to be replaced?
  
  
  
  If you can't tell the cam lobe is not touching the lifter, it's stuck down there. He said he cranked the engine for about 40 seconds but it did not start after he timed it. If he turns the engine CCW the piston will push the lifter back up but it won't move on it's own

• You gotta pull the head to confirm. That lifter may need to be replaced. Was the car running beforehand? Unless we can get a look at the head surface, I would say the head may be still good, but the bore for the lifter may need to be checked.  Have your friend remove the head, take the cam out and see if he can remove the bad lifter. The valves for sure will need to be replaced - also check the guides and seals.

  This is my car. Tyler is helping me out with it.
  
  The car was running beforehand. I had changed the injector pump because the one on there was leaking. I thought to just put the timing back where it was after I swapped pumps... Sadly, I didn't know it was a destructive motor.. Nor did I think to turn it by hand first to find out if everything was groovey..
  
  Live and learn i guess.
  
  Will i need all the valves or just the 1?

• Is it doing that with only this valve? I'd pull the cam and see if the valve springs aren't broken first.

  As far as i can tell, its only the one valve. The rest are all touch, and i CAN rotate this engine about 1/8 of a turn side to side, but then it makes that nice metal click and i know it wont go any further...
  
  I'm going to take the head off and bring it up to a friends shop and have him check it out. I want this motor to last, and i've already spent a lot of time on the car, so I might as well do it right.
  
  Btw, the motor has less than 50k original..
  DANG!

• Just the one valve. Do us a favour and remove the head. Get us some pics of the suspect area. At this moment in time you may look into doing the timing belt and water pump, as your car is going nowhere at the moment....Even better, do the HG as well. Then you're set.
  
  It's not that bad. It could have been running, then then the belt skips a couple teeth, and then you're into more $$$.

• Only 50K? Then skip the waterpump. Upgrade to the 1.9 HG though..

• Before you commit get a pricey replacement Jonas I think I might have a head for you.

• Ok, got the head off. Taking up to the shop now to have it checked and the valve(s) replaced.
  
  Here are the pics. I wont be able to check the responses to this for a bit but dont make me cry too much k?

• From what I can see, doesn't look like there was any piston to valve contact.

• sounds like the problem i had a while back with mine.. had it fixed.  one valve was almost 'dangling' there  :lol:  car drove alright and mileage was okay.  power was decent... just some weird noise at idle and part acceleration.

• From what I see, all looks good. Get that one valve fixed and put on a 1.9 HG and new timing belt. You should be fine.

  lol, you and your damn 1.9 HG.. If I knew what the heck it was.. i might be inclined to try it..
  
  But at this point, I just need/want the car running asap.

• He has a solid lifter head, a metal HG is probably out of the question (yes I know it can be done)
