Earl brown timing cover cam button wear

[Toby_Goodmk]

I recently got this timing cover and after reading about cam button wear I thought I would check mine. So a couple questions.

1. How can one tell if a true earl brown cover

2. Is this wear excessive?

I plan on using a roller cam button

Thanks in advance

I'm sure Earl will chime in and know if its one of his covers(unless he's on a world tour doing porn).Normally if you go with a roller cam button it will not wear anymore but I would wait on Earl to decide whether its worth using or not.

I have done ALOT of timing covers over the last 26 years and I always machine the thrust bumper surface flat. I would think Earl does the same, too. A few minutes on a mill or even a disc sander would fix that. Be sure to clean it up good, though.

Thanks on the reply. I have a cam I am looking at with Webber on a billet unit which they offer to machine the cover at no charge. If this was one of Earls I would think it would have been machined. This wear would have occurred rather quickly as the engine only had a few thousand miles on it. Hence the reason I wondered if it was even an EB cover which I was told was.

When I had Earl do one for me,I was under the assumption he normally used NOS GM covers.

He does use NOS GM covers

welp, then this was not an Earl Brown cover....geesh.....It was a used cover which was painted silver.

Well can anyone tell me what Earl does to make the flow a little better? I am into this cover deeply (wont go into exact details publicly) so I cannot afford another.

He has a write up somewhere it might be on turbobuicksdotcom

PM Earl, I will tell you he has a lot going on right Now, but he WILL get back with you

The weber billet requires a 2.740" depth 1" spot face. Earl does not do this mod as only the billet cam from weber needs this done. I sometimes use there A kits with my custom billet cams and Earl will spot face the cover for my customers. The cover does not look like one of Earls. I compared it to one of many I have in stock. Are you running the stock cam button? That would cause the wear especially if it was used. Earls work is within the oil pump and cleanup of the cover. They are all I use and recommend.

 

[Toby_Goodmk]

Thanks all. I have pm'd Earl for his advice on my issue. Dave, I am going to run a 212/212 or 210/215 comp cam with morel lifters. I had a couple conversations with some people that believe that for my needs a billet cam is overkill.

As for the cam button, it was a spring loaded cam button that appeared to be roller type. Everything with my prior build was a disaster so I cannot comment if it was the correct part or not.

That's not one of mine. The only vendor that has covers done by me is Dave Husek.

It looks like you ended up with a used cover. The only way for that spot to wear is with an original hard plastic cam button. If you tore the engine down and found a roller button, it's not possible for that cover to have been new when installed.

An easy way to tell if any flow mods have been done is to look at the top oil hole that feeds the engine. If it's 1/2" and radiused, there's a good chance there's been some flow mods performed.

Before you consider using that cover again, I'd STRONGLY suggest removing the filter adapter and inspecting the gears, gear pocket, and relief valve.

Thanks Earl,

I spoke with Dave this AM about some things about this cover. I got this cover off the shelf and it was told to me that is was an EB. However I have discovered a few things about the build that have proven to not be accurate as well, so I am not surprised. I got the last NOS cover that Weber had today.....printed your instruction sheet, and plan on carving it up tomorrow. I will say this.,,some oiling mod was done to the oiling holes as they look to be opened up to 1/2". Thanks for the response.

no more crap, going to use the EB method of porting tonight with EB's suggested drinking routine. Got the last of the NOS ones from Weber today.

 

[Toby_Goodmk]

Time to get busy with the mods, I am in timing cover haven!

 

[psycho6cyl]

depending how much that cover was you should have just purchased one his covers.

 

[Toby_Goodmk]

1/2 the price, and a learning session for me as well.

 

[psycho6cyl]

ohh thats good. when nos word is used prices go up. not saying weber is like that

 

[Toby_Goodmk]

yea, if it wasnt 200, i would be having earl do mine. Nothing against him, its 220 saved. I need it !!

So how drunk did you get doing the cover.Did Earl mention the couple of BJ's that you are supposed to get in between steps,if not you may have not done it right.
