Questions & Answers

Do you want to machine one or both sides? If you have Are you aware of any "001" inaccuracies?

For the price, one side is machined in, while checking the cylinder head for warping and not seeing feelers slipping through, it is a great buy

Is there a case for it?

The CD is just in a cardboard sleeve, without any case. To avoid warping, it is technically recommended that the tool be hung up to avoid it falling. Definitely impractical and no mechanic does a job like this, but just letting you know

Would it be possible to use it to check flat grills for warping. There will be a temperature of about 400 plus degrees on the grill when you look at it. ?

Because it is made for automotive use with checking heads at cold temperatures, you would have to use it with discretion.

This is one of those things you wish you had bought sooner! For now, I have used it only to check the straightness of several pairs of aluminum cylinder heads
4/5

As I was checking the first set of heads, they were warped beyond specs and the owner had installed it more than once, causing sealing problems. As I was checking the second set of heads, they were perfectly flat, which left me confident that all my time and money would not be wasted. As soon as it was completed, there were none of these problems. will not be able to verify the accuracy of this tool unless I buy another one down the road. However, I believe it to be made in the United States, so that gives me positive feelings about that. In terms of the tool itself, it is robust and should provide many years of service.

In the end, it did what it was supposed to
5/5

Over the weekend, I let my brother borrow my old Corolla. caused an overheat on the way home on Monday after making it to work. To fix the car, I borrowed my mom's car while I paid one of my brother's friends. Neither he nor the woman knew what they were A variety of methods are used by it Designed to stretch so much that only one bolt can be used on the head gasket, the steel bolts are designed to stretch too. Even though I own the repair manual, he must not have taken the time Once again the overheating led to oil flowing out the corner where the head and the block meet. In the end, I disassembled it myself and found it to be a bad design. With this straight edge and a metal feeler gauge, I sanded the head deck of the block with a piece of 2x4 and some sandpaper, and I sent it to NAPA machine shop for replacment. As specified in the spec, There was a line of 001" over and over again. It is most difficult to make the gap with "002" at the worst part. By the time I was done, it was I replaced the gasket and the head bolts with a new set of mls gaskets and put the head back on. Although it never leaked again, I'm guessing the oil seals around the valves were bad because the aluminum head got so hot so often that it let out blue smoke out of the tailpipe and lost oil over time even though it had never dripped oil I sold the car just above scrap for a bit over the straight edge, but it seemed to be a good deal. I would be concerned that an aluminum head on a cast iron block with an mls gasket and expensive head bolts would be way too fragile for an engine that produced 90 horsepower. I still have the straight edge, and the gasket does not leak anymore, nor does the car overheat as much.

After looking at many straight edges, this was my favorite because I needed one that I could attach to my There are many straight edges available, but I liked this one the best as I was going for a "straight edge," rather than In terms of height and thickness, this product is very substantial
5/5

It meets all the requirements to be used in a garage shop. Overall, I was satisfied with the packaging. I am not sure as to why there are complaints about the packaging as it would be hard to damage the straight edge unless you did it intentionally. Having a hang up hole is convenient when it comes to storing. I received the order ahead of time. Everything was better than I expected. Despite the fact that price was reasonable (no small point to me), it was good. I appreciate your kind words,.

The tool is very good
5/5

This is a tool that will be very useful for any professional mechanic. Sadly, very few use or know what it is, but if you work on heads you will need this.

The item is excellent for the price
5/5

I purchased it so that I could check for warping on the cylinder heads of my engine. As I expected, I was able to identify warped heads without difficulty. As soon as the heads returned from the machine shop, I checked them with this straight edge to ensure they were true. The fact that the straight-laced government isn't corrupt gives me confidence As far as the edge itself is concerned, it 's Keeping the thin edge of the machined part oiled to prevent corrosion is a nice touch provided by the plastic sleeve that covers the machines edge. I consider this to be an excellent product for the price.

Everything seems to be going well so far
5/5

This is the way I tested the difference in valve height in a DD13 recently. A total of three cylinders' worth of valves will be affected. The straight edge has a cover over it on the precision edge, so it is packaged in a cardboard box. Everything seems to be going well so far.

The purpose of this purchase was to inspect the head/block surfaces on my Subaru
5/5

This is to be used to check surfaces of Subaru engines' heads and blocks. The straight edge is of high quality and is suitable for this purpose.

A 24 inch screen is all it has
5/5

Made of a sturdy metal, it is extremely well-made and can be used for a lifetime with just a little care. It is just that when I ordered it, I thought it would be Spending the money I did was not a regret However, for those on the outside A 2' plastic $5 one I bought for handling really rough stuff made me very happy. 'Indoor shop tools' are those used in indoor shops. I heard that one was sold under a different brand name and that it was quite expensive. Yes, it is worth the money I spent on it.
