Ok, I have been thinking of this for a long time and never posted the question... how can you tell the difference between a 216 and a 235 ci engine?? im not sure if I have a 216 or 235 and I do have pictures of the engine on page 11 i believe. the old screen name is 6400chevy. you could probably find it on the search thing a ma bob.... and thanks for your help
Look for the serial # of the engine (passenger side just behind the dizzy). Let us know what it is and we can tell you what year model and displacement it is.
engine O.K., sounds good! I will have to do that on my day off.... before I get to work its dark, and when I get home its dark and I have no patience looking for flashlights..... And hopefully it warms up a lil bit so I can pull the engine this tuesday and wednesday and get it cleaned up a lil bit and tear it down and rebuild it over the winter.... now if only i can get some heat in my shed . but yeah, I will get the serial number for you guys this tuesday.
How To ID 216 Vs. 236/261 It's pretty simple : look at the right side of your engine , there's a vertical sheet metal plate on the side , if it's tall and the spark plugs stick through it , it's a 216 , if it's short , you have the newer (?better? maybe) 235 engin with full pressure oiling , a good thing in most cases . Wo ~ I get away from the 'puter for a gew days and you guys leave me way behind....
Aren't the valve covers also different? The 216 would have bolts through the top of the valve cover,235 bolts around the perimeter.
Rockerbox Variants Well yeah , sorta - kinda : early 235's still had the two acorn nuts on top and these old nails got changed 'round so much no one really knows what you have untill you , personally have checked......
thanks for the information, I will be sure to get it to you guys asap so someone on here can help me out with it... I think its a 216, it has lil or no oil pressure while its at idle. and with these old mechanical fuel pumps on the block, how can you tell when its starting to go out? do you get gas in the oil? I have been having that problem ever since I started it up. hmmmmmm another trouble shooter
Old StoveBolt Engines O.K. , not to worry ~ zero oil pressure is normal on the 216 and common on the later 235's too so as long as the gauge registers _something_ above idle you're good to go . usually if you're _very_ observant , the oil pressure gauge will rise like .004" off the peg @ idle , this is plenty The most common fuel pump failure mode is fuel in the crankcase so if you've got gassy oil , do a HOT oil change right now and get busy rebuilding the fuel pump if it says " AC " casted into it or has a glass bowl on it , otherwise just get a nifty new one from Airtex (NAPA etc.) right away as gassy oil can ruin your engine in short order . Consider buying a dual action fuel pump as they're cheap and will make your wipers work like electric ones....
