Problems You’ll Face While Using Engine Assembly Lube

You can’t expect a perfect engine build without using engine assembly lubes. But there are parts that make it hard for the lube to reach. Some parts won’t hold the oil for long.

What we’re trying to say is there are problems you need to acknowledge. That’s why we came up with some ways to address these problems.

Hard Engine Turnover

A lot of people tend to use SAE 30-grade motor oil and STP for building their engines. We’ve seen people who love to put that stiff thing all over their engine.

But that very stiff goo can lead to hard engine turnover problems. The engines won’t have sufficient lubing when you follow this method.

Nonetheless, we figured out an easy solution to this problem. Professional engine builders pre-lube the engines beforehand. So, we thought why not pre-lube the engines by using pressure?

To pressurize the oil lineups, you can spin the oil pump for some time. That’ll give you the oil pressure you need.

The bottom line is, that you can use oils of indistinguishable viscosity. If you do it right, we can guarantee you that you’ll solve this problem once and for all.

Oil Drainage During Storage

Your flat tappet lifters, camshaft lobes, and pushrod tips don’t really know what lubricants feel like. They’ll only get a splash of lube while the engine is running. And even that happens if luck is on their side.

We know the obvious thing. You can easily push some lubricants over those areas. But that doesn’t really solve your problem. You see, the oil needs to be stored for quite some time in those areas.

So, the best thing you can do is to use grease. If you think about it, grease is basically oil mixed with a soap-like substance.

It makes sure that the oil is always there in the suspension system. Later on, when there are enough heat and motion, it releases the oil to do its job.

Racers use 60 or 70-grade heavy oil grease for their vehicles. Some even opt for new generation gels. But you don’t need that sort of thing.

When choosing grease, you’ll need to keep two things in mind-

Oil-soluble

Oil solubility is a must for engine grease. The days of white paste grease are over. The main reason behind this, those are not oil soluble. Moreover, the oil filters will show a lot of white residue. 

Although if you’re someone who works on their engine every single day, that’s completely fine. But here’s the thing: most people won’t even give their vehicle servicing. 

Extreme Pressure Grease

Generally, it’s a good practice to apply extreme pressure grease on engines. It’s more than important for people who have stiff valve springs and high lift cams.

The reason behind this is, that not many greases can’t really ensure the protection of the components where the area is small.

So, when you use extreme pressure grease that’ll make sure to protect every single component. Think of it as cheap insurance for the components.
