ok...the question was referring to a stock 1600, wheras the motor you are talking about is not a stock 1600 as you have replaced the pushrods, presumably cut them to length to set up valve geometry? Did you need rocker shims? Without doing the maths, my immediate thoughts would be valve to piston clearanace as well. Have you/your Dad looked at this when building the motor...I know you say it has been running for years...but I'm curious about it.bugger 61 said:1:4 ratio rockers will work on a standard 1600. My Father is doing just that with a set of Autocrafts. He is also using stock springs, as he doesn't rev his bus through the roof, but he is using chro-moly pushrods and lash caps on his valve stems. Must have had them fitted for three or four years now, with no problems at all. If there is any doubt about the springs binding, before firing up, rotate the engine by hand to maximum valve lift, and make sure that a ten thou feeler blade WILL fit between the spring coils, and you'll be OK.
You buy a set of aftermarket (cut to length) pushrods which have one end disassembled.64J said:how do you work out the length of the push rods needed if using 1.4 rockers? tis on a ad case so 69mm crank?
No problem, set the valve geometry as above with the hardware fitted as you are going to run it, any changes from stock valve train you should check and adjust the valve train geometry to get the best from your engine.deejay451 said:Sorry there was something else. I definitely fitted lash caps!
