02 Escort jumped time-bent valve

[caster27]

There's a bent valve now. Without tearing apart the engine to see if there's more damage I'm not sure where to go from here. I don't know enough to know how to do it and can't have it done. People are telling me just to replace the head. Others are telling me to put in a used engine. Just looking for some suggestions, What would you do?

That is unusual since its not an interference motor in an escort.

That was what I thought also.

Wasn't the last CVH engine that was interference the 1.6L or was it the 1.9L ?

Looks like the SOHC engine will bend valves.

That was a 1.6L

Later versions of that engine were specifically designed to "freewheel". I just don't know what year this went into production.

Looked it up on the link I provided and the 2002 Escort will bend valves if you have the SOHC engine. The DOHC engine will not bend valves. They are both 2.0 engines.

I discovered there is a lot of misleading information out there. We just replaced the timing belt on my brother's '97 Escort yesterday. The timing belt had lost about 6 or 7 teeth and the engine had jumped time significantly. He has the 2.0 Liter 4-Cyl. SOHC engine and thankfully that is a free-running engine. 2 hours and $30 bucks later and she was back up running again.

I'll share what I learned: I've always used the Gates website as reference to determine if an engine was interference or free-running. When he first called and told me his car wasn't running and that he checked the timing belt - and had found it had lost 6 or 7 teeth I went to the Gates website to see if it was an interference engine or not. I used the link to the PDF "Timing Belt Replacement Guide" on this page:

Gates Timing Belts

On the top of page 8 of the PDF, it lists Ford Escort 2.0 Liter 4-Cyl. SOHC '97-'00 and '01-'02 as non-interference (or free-running) type engines. (note the lack of an astrix symbol and see definition of astrix at bottom of page) further note that there is no recommended replacement interval it just says to inspect the belt at 120K and replace only if needed.


But when I went to the parts store to get a new belt it showed up as an interference engine on their computer, which made me a little nervous...

After I got to my brother's place and we were putting on the new belt I told him that the parts store computer said it was an interference engine even though the gates website said it wasn't. He said he also went to the gates website and it said it was an interference engine as well. I said no it wasn't I checked before i bought the new belt. After we finished up with the car and got cleaned up we went inside to the computer. He showed me that he had used a different link on that same page that read:

Got an Interference Engine? Find Out Now

When we looked it up together using that look-up tool (and I recognize Mark's chart) it said it was an interference engine but lists the same engine and belt part part numbers as the PDF.

Since the engine ran fine and the car drove well after re-aligning the timing and installing the new belt I tend to think the PDF on the gates website is correct and the both the look up tool on the gates website and the parts store computer were wrong.


Maybe someone else has some better info on why the two charts seem to contradict each other...?

I have a 99 ZX2, and someone told me on this website it's a ZTEC, and that all ZX2's are Ztec. It's a 2.0 that's all I know about it. It jumped time and I took it to a mechanic and he said the engine was a total loss, not a freewheeling engine. I was out over the road driving an 18 wheeler at the time and before I left I told the guy to go ahead and junk it, although I never gave him the title. Two months later the shop owner calls me (it was his son who was running the biz while he was semi retiring who told me it's junk), and says we can fix it, it just needs a timing belt. I had written the car off, forgot about it and after having it fixed, it's been running great for 18 months now. I guess the short of it is make damn sure it's non-interference motor cause I almost lost a nice car (I think the owners son wanted him a ZX2 for nothing), thank god I never gave him the title.

ALL Escorts except just a few of the 1st generation have a non interference engine. I have an '88 that has 492,000+ miles on it, it broke a timing belt once several years ago. I had it towed home, put it in the garage, lined up the timing marks, put a new belt on it and fired it up. I'm guessing that was about 200,000-250,000 miles ago.
