I'm adjusting valves on what I was told is a 1.8L engine. I've checked 2 exhaust valves and found them to be 0.006 instead of >= 0.008 for a 1.8L.

How do I confirm that its a 1.8L engine? Below are the stampings on the top and the bottom of the case.

Thanks,

EC means 1.7 but a PO could've installed 93mm p&C's for more hp.

Adjust them to .006

according to this site's 914 info page, under engine serial numbers,

EC = 1.8L

W,EA & EB = 1.7L

Heck, thats what happens when I just git up and am drinking my first cup.....

Thanks!!!!!!!

I've been up since 11pm....working third shift has some perks...I get to be the 914 nut while everybody else is reaching for the coffee

The valve clearance is the SAME (.006") for all the engines w/o sodium filled exhaust valves. I dunno where you got the bogus information, but it should be corrected before others are misled. The Cap'n

I was looking at a printed tech article that I got with my 74; not sure where it came from.

quote from article:
First, general rules:

Be sure that you use the correct clearance values for your engine: .006 INTAKE... .008 EXHAUST (for 1.8 and 2.0 litre) (.006 BOTH for 1.7 litre)

However, from PP tech article:

quote from PP tech article:

Engine Model Intake Exhaust
914-4 1.7L 0.15mm / 0.006 in. 0.15mm / 0.006
914-4 1.8L 0.15mm / 0.006 in. 0.15mm / 0.006
914-4 2.0L 0.15mm / 0.006 in. 0.20mm / 0.008 in.
END QUOTE

So I should do both intake and exhaust to .006.

Set them at .006 as the Cap'n explained..

EC is a 1.8
EA is the 1.7

Either way the valve adjustment is the same.

OK, so I adjusted the exhaust valves to 0.006. Not an issue since the engine is sitting on a stand in the middle of the garage.

Later I checked with my Haynes 914 repair manual and they group the 1.8L engine with the 2.0L at 0.008 for the exhaust. I just love when information from different sources agree.

.006 just like my Type I.....
