Engine Rattling

[KuroNekko]

I remove the cover when I wash my engine.

I mentioned leaving it on to help prevent water pooling in the spark plug area. It shouldn't happen, but sometimes it's better to be safe than sorry. I've noticed a lot of issues cropping up on a Grand Vitara forum I frequent from the "coil on plug" spark plug boots failing. Some people have posted pictures with rusty contacts inside the boots - so water has penetrated that area.

I believe it and I know that water pools in the recessed area where the coils sit. However, the coil boots are supposed to seal the spark plug hole. Regardless, it's why I have rags and soak up the pooling water completely. It's also advised that you run the engine shortly after and have the engine heat evaporate the excess water.

Each to their own.

I on the other hand never take a hose anywhere near my engine bay. Vinyl/rubber detailer, degreaser and some elbow grease:

How do you rinse the degreaser?

That looks great bootymac!

I've heard of a technique of spraying degreaser and using steam to 'wash' it off that does great. I've also heard of a method by which you actually spray on degreaser and water and drive around for 15 minutes (saw it on a prelude forum). I've never tried these methods, but I know steam can do a really nice job.

How do you rinse the degreaser?

Wet rag, but honestly I've rarely had to use a lot. The metals in my engine bays rarely get dirty enough to warrant it. I'm not entirely sure why

I rarely ever wash my engine. Probably once every couple years if that.

Take the engine cover off and drive around without it, if noise goes away then that was your problem. Engine cover is only there for looks.

Problem solved. It was the tensioner. Replaced under warranty, noise is now gone.
