Silly question- how many valves do I have?

OK, just visited the Pelican Parts buyers guide
http://www.pelicanparts.com/techarticles/944_buyers_guide/944_buyers_guide.htm

and read this:

"1989 1991 (944 (1989 only) and 944S2 (1989 1991)

Standard 944 had a 16-valve, 2.7-liter engine; the S2 had a 3-liter engine. A Cabriolet version was introduced in 1989 (S2). 944 production ceased 1991."

Uhhhhh.....I have an 89 944 NA with the 2.7 engine, but I thought that, despite the rarity of my engine and its position as the last of the 944NA line, it was still an 8 valve....right? Am I reading this wrong or maybe it's a misprint or something? I am super confused now....

Where are the spark plugs in your head?

Thru the valve cover... 16 valve head.

Drivers' side of the cam tower, buried down low?..... 8 valve.

I think that is a fair way of telling.

OK, by your logic I have an 8valve, which is what I had always thought until tonight :-)
So I guess the buyers guide has a typo?

Could be. I always thought the 2.7 was the 16 valve, but they are so rare I've never seen one. I know the 3.0 is the 16 valve. Maybe someone can be more definative.

I believe that to be the case. the 2.5s (turbos incl) all had 8v, with the S and S2s having 16. so your supposition was right

You can see a pic of my motor here:

click on picture 5 to see the motor....the plugs are just under the fuel rail, you can see the plug wires leading there.

Yup, it's an 8-valve for sure, no doubt about it. Great engines by the way, not the ultimate hi end power of the S or S2 versions, but still lots of torque right where you need it and can use it, and still quite fast. Remember, these cars were able to EAT the six cylinder 240-Z on the streets and on the tracks.

I have a 1984 normally aspirated 8-valve that looks just like the one in the photo, and I also have a 16-valve 1990 S2. The '84 version is 2.5 liters. The 3.0 liter S2 is quite a bit faster, but true over the road driving wouldn't put it at that much advantage over the baseline 944. They're all great cars.

Regards, P

Your car is the one year only 89 2.7 liter 8 valve. That head is quite valuable to a lot of 944 turbo owners that are doing significant modifications to their cars. You have bigger valves, and different DME mapping as well. The S, and the S2 had 16 valves, obviously. All other 944s had 8 valves, all being 2.5 liter engines, with the exception of the 89.
