Running EJ22 without timing belt cover
Posted 23 October 2005 - 07:46 PM
The parts of the cover behind the cam pullies have notches to help allign the pullies, but I was figuring I could make a tab or something to replace that. The Timing marks for setting the timing are on the font cover, refrencing the crank pully, but those are'nt really necacerry because the EJ motors don't have a disty.
One other fact to consider is that the motor will be in an offroading car, so mud and water will be encountered. Will this break the belt, or will debris be thrown free?

Go to a junkyard and find a used set.

There is entrances for water around the cam angle sensor, so I'm afraid that muddy water will be held in there, Fubar'ing the seals. But I'm also afraid of a rock getting caught and breaking the belt.

If it is an earlier non-interference engine, I say run without the covers and carry a spare with you at all times. Without the covers, the timing belt can be changed in about 10-20 minutes. We run without covers on our race prepared EG33. It makes it quick and easy to confirm timing plus it looks cool :cool:
If it is a later interference engine, then the decision becomes more difficult...
edit; I just read in your sig that the EJ is coming out of a 92... I say strip them...

I appreciate the input.
Any more votes?
Oh, BTW, the right hand side head got hot enough to melt the plastic of the cover around the 2 bolts that hold it to the head, so its alignment is now suspect when I reinstall it. Plus, the black plastic looks cheap against the polished aluminum block. I think that anyone can tell where I'm leaning, but I could be swayed by a horror story of open timing belts.

The worst that can happen if you lose the belt is that the engine cuts out... Now granted this will happen on a 15* night with 20 MPH winds and rain and sleet and snow, but you seem like the adventureous kind of guy...
When I change belts on my street SVX I plan to leave the covers off, and I'm debating it for my 97 Leg even though that IS an interference engine :-\

My recommendation to leave them on is due to the fact that any dirt and other junk that gets in contact with the belt, pullies, etc will shorten the life of the belt, and the idler pullies.
If you don't care about that.....then leave them off.

I will run without covers untill I get back in the money again (spent 600 on this sucker just in parts) and put new covers back on. Josh has a darn good point... The new water pump will get its seals done in If I don't replace them and the Idler pullies/tensioner might get trashed too.
I'm going to be doing a 1000 mile no-clutch-dumps no booning break in period, so I should be safe without. But when I get back in the woods, the new covers must go on.
Anyone know how much they cost?

i run with covers no problems on mine for years, no problems. i drive off road, snow, mud, corn fields, etc, no problems.
