On the 1.8L BP engine, when you delete (remove) the OEM oil cooler/warmer that has the two rubber coolant lines, by removing the 29mm nut with a deep socket.

Would you still be able to screw a regular oil filter on and go on with your day?

Or will the thread be too long and the oil filter won't seal up properly without the cooler in place?

Need to know asap! thx

 

Use the search function.

But since I am in a good mood I will spoon feed you info.

You can remove it but you must use either the 1.6 threaded piece or cut yours shorter.

You are better off leaving it in place because it helps get to operating temp sooner then acts as an additional oil cooler. If you are worried about leaks just undo the hoses and reroute the coolant lines to eliminate the cooler. Why do you want to do such a thing like remove it.

easiest way to remove it: remove the coolant line from it.

 

Okay thank you. Lol sorry I normally search search search but I was on a short time span between picking up my sisters and having a car to decide to go get the 29mm socket or not. I appreciate your help and speed. Perfect timing =]

As for asking why do I want to remove it, Technically I'd rather leave it on, it saves me time overall not having to mess with it.

But the guy at the machine shop told me that because the engine blew up that I would want to definitely remove it or find a new one that's never been used on a blown engine before. He said that they are impossible to clean out and any broken metal pieces from my 2-3 pistons that exploded are likely to be within the oil cooler somewhere and he said out of experience that you can never clean them out completely and supposedly people have tried to use them again and on several occasions their engine wore out pre-maturely and had bearing damage due to the tiny pieces of metal within the oil cooler.

However, he wasn't talking specifically about Miata's. Maybe the miata oil coolers are able to be cleaned out... I've never taken it off to look at how much of the inside I can see or not. He was talking about them in general, for any make&model.

Have you ever run a oil cooler that had been used previously while the engine blew up and re-used it on a fresh rebuild without any problems? I'm pretty sure a lot of people have. I don't know personally. I was just going to delete it and keep the piece of mind. But that's the reason behind it. The machine shop guy was very knowledgeable and a genuine individual. What is your personal opinion on his theory? Or do you agree with that it's a good reason to remove or swap to a new one (If you can even find new ones these days)?

Thanks

 

At least he knows what he's talking about.

Mine had little bearing bits inside. I bought a new one , you can pull from a junk yard possibly if the motor isn't blown or find another used one.

 

While its more of an oil "regulator" than cooler It does help and serve a purpose. Id try and find a used one from an engine not blown up to put back on. Adding a real oil cooler on top wouldn't hurt either.

That being said IF you have to buy new.... the MSM/JDM NB2 oil cooler is a bigger unit, direct swap and half the price of the standard 1.8 unit. logic right?
