I was researching a problem with my 22RE engine and found this group.
My problem appears to be a common one; the timing chain has worn a
hole in the cover. The shop where I took it has told me that I'd be
better off either junking the truck or going w/ a reman engine. Any
advice from someone who has been there would be appreciated.

The truck has 210k miles on it, but I have only owned it for the last
6 months. I was on the way to work the other day when it stalled out
at idle. It started right back up, but ran rough. I drove it a total
of about 5 miles in that condition. According to the mechanic, I
didn't damage the valves (chain didn't break), but he thinks with the
mileage that I'd be throwing money away by replacing the cover and
chain.

Thanks,
Paul

That's a good question but really hard to answer. What condition is the
rest of the truck in ? How much is the repair going to cost ? Can you
purchase another vehicle for the price of the repair ?

If the truck is in good condition and well maintained it may be a good
idea to have it repaired. While you are doing the timing chain and cover
remove the cylinder head and have a valve job done. It might be a pricy
repair but you shouldn't have any more engine problems.

Depending on the cost of repair you may be able to purchase another vehicle
for less money. If you purchase another vehicle it may need just as much
work as the one you have now. Then you would be out the money for a second
vehicle and repair costs.

Attn: Mike

Have you ever ACTUALLY replaced a timing chain, without removing the head?
Also, the oil pan! Head item aside, how do you check (remove) any broken
gasket material and junk (metal particles ) that most likely have been
ground up and will wind up in the oil pan and subsequent pump!!. Maybe I
have done the last two the wrong way............

Might add, that the cost of the repair, if done by the OP (with help) should
not be much over $400.00, far less than the cost of a new truck!

Just my .02

I had my timing chain replaced at 125k as a precautionary matter. It cost
about $1500 to have the shop replace it. The truck still runs great at 150k
and I have no plans to get rid of it. In fact I have had people at the
dealership offer to buy it.

Hell no!! But you get people asking all the time if the head really needs
to be removed to do a timing chain. If you have the engine that far apart it
only makes sense to replace the head gasket as well. Also, with 210,000
miles on the engine, it makes sense to have a valve job done while it is
apart.



The first question I have is were did the ground up gasket material come
from ??? If you cover the front of the oil pan while you are scraping the
old gaskets off you should not have any gasket material in the oil pan that
you need to remove.

The second question is what are all these metal particles in the oil pan
that need removal ??? If you are talking about the metal from the timing
chain cover it is most likely in the oil filter. As it was rubbed off the
timing cover while the engine was running it was suspended in the oil, run
through the oil pump and ended up in the oil filter. That's what oil filters
are for. Any shavings that were too heavy to be suspended by the oil will be
laying in the bottom of the oil pan and will most likely get removed at the
next oil change. Any particles that remain will stay at the bottom of the
pan and will not be a problem.



Before any gasket material would be able to get into the oil pump it would
first have to go through the oil pump pickup screen.



Maybe I
Maybe..........

Yes, if the OP could do the work they would save alot of money that would
be spent in labor. The OP said they had taken the vehicle a mechanic, which
will be a bit more expensive.

I think the "Hell No"! and subsequent rant answered my question!!
Responding to a question with lack of knowledge and experience often leads
to embarrassment!

Sorry Bill, didn't mean to embarrass you......

""Chuckle".... I wasn't referring to me being embarrassed...... I have the
knowledge AND experience... Nuff Said!

Thanks for the info. I don't have the tools and knowledge to do this
job myself, so I'll be paying someone else to do it. This is why I
was (and still am) kind of on the fence as to my next step. What I
dont want to do is spend the money to have the timing chain and cover
replaced only to find out that the engine got trashed from either
debris from the guide that failed or coolant getting into the oil
pan. I also contacted a local junkyard that has what is "allegedly" a
good used 22re that I can pick up for abot $450, but I'm not crazy
about that option either. I appreciate everyone's input.

check out Partsdinosaur.com, he sells on ebay, but the prices are the same
and you get the parts faster without having to bid. Also make sure you get
the steal reinforced guides and not the plastic ones like the original.
