Checking valve clearance – S54

Hello,

I’m want to check valve clearance on a S54 engine and to do that I need appropriate feeler gauge set. Getting it seems to be not so easy.

I rang BMW service in Cork and they will not sell it.

The thickness to measure is between 0.18 - 0.23mm and 0.28 – 0.33mm, so basic feeler gauge set will not do.

Anyone would now where I could get a proper feeler gauge set or even lend it?

Or perhaps there would be someone in Cork area who would check the valves clearance for me :D

Fairly sure a guy on the forum "narusa" will lend you this set for €50 quid or so.

Davemsport on driver is in cork, on driver and should have what you need as he's built an s54 I think

Bart in Jdm garage builds engines he more than likely has one worth a shot

You can buy the full shim kit on ebay uk for about £85, they are not listed as bmw shims but are by all accounts the same. As for a feeler gauge, have you tried brownlows, Munster tools, joe desmonds.

Ardfallen in ballycurren have a mechanic working for them who rebuilt his own s54 also if you wanted to try them/him.

Thank you lads for all your responses. You gave me a number of options to try so will definitely find something. I'll try to buy the feeler gauges first. Will let you know how did it go.

Hi there,

I’ve checked clearance and shims on my engine and wanted to share the results with you and also have some questions.

I think the results are not too bad. I was told that the engine has done 60k miles, but was wondering if anyone can tell anything about it by looking at the results? Would that be expected for 60k miles engine?

Now, it’s obvious that I need to adjust the exhaust valve 1F (Cyl.1 Front). But what I am not sure is if I should adjust valves which are on the edge, like Intake 3F, 4R or Exhaust 1R, 3F?

They are perfect. Just swap out the one thats needed
