Can I use modern brake cleaner on exterior engine parts?

I use brake part cleaner on lots of things. It should be fine. Note- this is just personal experience. If someone pops up and says it's detrimental, I'll certainly listen.

Helicoil installed from other side?

You could partially enlarge the hole (where the tread stripped). Place a round steel nut into the enlarged part. You could also fix the nut with glue

Helicoil installed from other side?

Well, I did it, and it was one of the most straightforward fixes possible. Here's what I did... So I bought a cheap M6 1.0 kit for $27 NZD. Clamp was secured in a drill vise so it wouldn't move. I ...

Helicoil installed from other side?

You comment that this is M6. Presumably M6×1. For a helicoil you'd need to run a 6.3 mm drill down there and then you'd be tapping to something like M7×1. M7 screws are rare as ...

Do any new cars come with cast iron engine blocks?

I believe you are probably asking if cast iron is still being used in cylinder blocks, because to my knowledge, steel has never been used in mass production towards that end. With that said, cast ...

Helicoil installed from other side?

You could take it to an engineering company and get them to fill the hole using a welder, then re-drill and tap to the original size if your helicoil doesn't work.

Helicoil installed from other side?

Can you live with ugly but strong? You could put a longer bolt through if there were wedge-shaped shims on either side. You could cut and shape these just from some bar stock by hand - no precision ...

Helicoil installed from other side?

Get a quick-release skewer. Fit (grind) an angle on a thick aluminum washer so that the skewer applies correctly. Solder fitted washers to both sides of your clamp with argon welder. That'll be ...

Helicoil installed from other side?

From what I read, it seems that primary problem in installing the helicoil from the wrong side is that the tang would be left on the entry side of the helicoil. How about just installing the helicoil ...

Aluminum parts on motorcycle oxidized after washing

Usually this is either one of two things: 1) the soap used was not suitable - may have had a bleach or some other chemical which may have attacked the aluminium surface, 2) these are just simple ...

Helicoil installed from other side?

Your last paragraph sums up the problem exactly. The tang is usually either left or broken off at the very bottom of the hole and causes no problem as it is not normally reached by the bolt. If you ...

Aluminum Anti-Seize - Suctioned Bottle

I'm no chemist, but the safety data sheet suggests the presence of 10-30 % calcium oxide by weight. Calcium oxide appears to be hygroscopic, so just like old brake fluid in a bottle it absorbs ...

Cast iron vs aluminium engine blocks

The use of aluminum is related to power and fuel octane satisfaction. You need to increase compression with aluminum heads to get back to the same power level as you had with a cast iron head. ...

Why are valve covers made of plastic if they warp?

While the valve cover is technically "plastic", it's actually a polymer which stands up to heat pretty well. While they don't usually warp, they can warp depending on how hot they get. Why ...

What could be the cause of damaged wheel nut surfaces on aluminum rim?

Ok, now I have a replacement rim for free. The shop assessed that the damage isn't a hazard to traffic safety, the rim can still be used, but since this might affect the resale value of the car, I ...

Same as steel panels, only if you use wire disc on angle grinder, use a softer brush. Everything else the same.

Can I use modern brake cleaner on exterior engine parts?

Brake clean works fine but evaporates quickly (the whole point of it), Varsol (Solvent) or something similar works better for cleaning and then wash it off with brake-clean.
