Title: Alfa 33 1.5 Boxer Cam belts?
Post by: Brooke on March 03, 2010, 11:49:21 PM
Do these engines use cam belts or firing rods?

It is the standard Alfa 33 1.5 Boxer engine with twin webers

At the risk of sounding like a moron (just for a change).......

-What the hell are firing rods?

-I don't think they made a 1.5 QV engine, only the 1.7?

But if it's the standard 1.5 engine, then yes, cam belts.  Didn't you see them when you were looking for your misfire?   They're easy to change, but a little time consuming.

Post edited, firing rods, well I am not sure on the name, they are an alternative to a cam belt on some engines according to a friend of mine who races escorts.

Didnt go near the belts when checking out the misfire, I am assuming they are hiding under the black cover between the engine and front grill? the other two belts that I can see are A/C and Fan belt

You can un-edit your post.  Apparently there is a 1.5QV.  And I have one in my driveway.

I was a little confused.

Yes they are hiding behind the black covers.  I'm mechanically inept and I recently managed to change mine, as well as the tensioners and water pump.  Worth doing if you don't know when yours were done last.

Guessing firing rods = push rods.  For engines without an overhead cam (or multiple).
