bent valves Head gasket??? Whats going on here??

OK, I have 1999 escort se sport with a 2000 split port induction, 2.0 that lost a lot or power... suddenly. I had to go to work so I drove it like this for a week.( I know, not smart) I had been having "power issues" from egr valve and Iac acting up. Had a check engine light for that. Well fast forward.... day five I notice tail pipe is sucking a little. I think jumped time! Then notice water is low... I think BLOWN HEAD GASKET!

Car has NOT over heated..

Fixed timing...tension pully was loose, belt jumped three or more teeth. Will a blown head gasket cause three of the four cylinders to have low compression? 1=140 2=50 3=15 4=50 Pretty sure I did the timing belt right, actually did it twice to make sure....easiest I have ever done.

Can I see bent or stuck valves if I remove the valve cover?

I would say bent valves look odds on.

Never worked on the 2.0, but general rule of thumb is if the valve doesn't make contact with the rocker in the rest position, or the lifter is broke, that valve is toast.

Okay thank guys. So I'll remove the cover today and see. Could I remove the rocker arms and measure the valves with calipers for height? Or must I rotate the cam? What would be a "not obvious" sign a lifters broke?

I feel it worth mentioning there is no noise while trying to crank. Thanks again fellas..... be right back...

See what you mean on interference or not .Some say it is but seems from the majority that it non interference which is good news for you if true .You would need the head gasket to be blown in two places to affect the three cys .I think it's a head off to be certain and reveal the problem .

The 2.0L engine in your 1999 Ford Escort is indeed listed and an interference engine. Broken timing belts on interference engine often result in valve damage. To begin to try and determine the extent of the damage I would recommend to install a new timing belt and then check the engine compression. Mileage is high but if your Escort is in such good shape it may be worth it to repair the cylinder head if damage is found. "

" all the 2.0 engines are non interference engines.there are relief slots cut in the pistons so there's no collision with the valves in the event of a broken timing belt. doesnt matter if your car is a lx,se,or zx2 have your mechanic replace the belt and you'll be fine.just replaced one this past summer on a 98 2.0l dohc dx2 with no problems,cars motoring fine.

Re: bent valves Head gasket??? Whats going on here??

Update: I took the valve cover off and the rockers and removed lifters. All look good.. (like NEW)

I measured all the valves from the machined suface the spings rest on ... TO... the retainer on top or valve with calipers .... ALL were the SAME!!! 42mm "ish"

I'm excited but not even sure this even matters....hahahaha

Thinking about telling mech to put a head gasket on and see if they see something when they remove head.... I don't know I'm lost

Re: bent valves Head gasket??? Whats going on here??

Now that you have fixed the timing issue, does the engine run now?.

Have you retested the compressions and have they remained the same on each cylinder.

Would be strange for 3 cylinders to be low comp with a blown gasket.

I didn't check compression before... wish I had....

Car does not run still. Drove it with lost power then it REALLY LOST power.... turned it off and it has not started since...( before time belt)

Update: Strange but not impossible is what I'm hearing.... sound like you feel the same way Big Block....

Also when I got the car the Rad was clogged with peanut buttery STUFF... maybe that weakened the gasket with all the flushing.... hell I don't know... I'm talking out my A$$ at this point.......

Ok that doesnt sound good with sludge in the radiator. I think there is enough wrong to say it would be time to pull the head and have a look in my opinion.

Engine not running, timing belt slipped 3 teeth, low comp on 3 cylinders and sludge in the radiator. I think next step would be remove the head.
