Hey all;
New 914 owner here. Just got a '71 1.7 with no compression in cyl #3. Popped the valve cover and there is a broken spring. Anyone tried to replace this with the engine in? Got a manual that only addresses the situation where the engine in on the bench. Thanks all, hope the BBQ is going well. Matthew. |

QUOTE(r_towle @ Aug 19 2014, 09:01 AM)  I have had them break just due to age...no magic reason. Seems the pushrod may have been mounted wrong in this case. rich I could imagine that if a spring were to break, then the pushrod end could jump into & out of the rocker arm cup and tear up the pushrod. I would inspect the rocker arm cup for damage and pull the lifter and have a look at it while I was in there. I still have an extra set of stock pushrods and I believe some lifters around. I sold a different complete set of each to someone on here that was struggling with having hydraulic lifters vs non-hydraulic. I dont know if he ever used the set I sent him. |
