Timing Cover

Is the timing cover removable? And is it safe to leave it off if it is? Like forever lol

Yes it is removable, why do you want to take it off? If you have adjustable cam gears it would be better to just do cut outs to expose just the cam gears.

Wait... What?
I wouldn't leave something exposed that is so important.

if something gets in there it can tear things up really fast, but it looks cool.

well I want to leave it off, just because I have to do the belt probably, I have to take valve cover off first to see if it needs the belt, now my question is what should it look like just by looking at it with valve cover off, If I can take the timing cover off and leave it off, i'd rather do that

its gonna be really hard to look at the belt and tell if it needs replacing. ive seen ones way over that look perfectly fine :shock:

sigh this sucks, I know I can do it, I just am rusty. I hate doing timing belts, as far as I remember I think I need to. Pop the valve cover off, take drivers wheel off, and wheel liner. Then Take crank off, water pump, timing cover off. Then untension the belt. Then I have to install the one I have and install it from there, then I hate this part. Just align the etches for timing. Thing is I don't really know what a belt looks like when its bad, always delt with chains which is even worse for me to replace so I am thankful I got a belt system. Heres a question, people told me that the 1.8 is a engine that if the timing cover breaks and the engine is running that that valves will hit the pistons because the valves stop right? I really want to keep this engine as good as it is now. It runs fine pretty much except for some quarks.

Anyway. How much damage could it cause if I leave that cover off? Or can I just cut that part of the valve cover off where the timing chain is? WIll that do damage?

People cut that part off the valve cover all the time, the question is how well you do it. You could damage it yourself not using the right saw or just opperator error. Personally, I like to keep that part of the valve cover on to protect the timing gears, but I had the plastic cover removed to show off the gears. It is a better idea though (and I might do this soon for my rebuilt B18) to just cut around on that cover to expose only the gears but have the cover still protect a good majority of the gears. You asked what damage could leaving the cover off? Well, think about it, not much can get in there. I haven't had a problem "yet". The only thing to worry about is dust and water kicking up into there. So, if you live in a area that is normally has dusty air of high humidity its probably not a good idea to, cus notice the plastic covers had rubber seals against the mount and block to keep such things out of the timing components. And one more qeustion you asked that really confuses me. You said that if the cover breaks on B18's while it is running the piston's will hit the valves? That dosen't make sense, how could that happen with just the cover breaking off? Good luck man
