captainkim Posted January 21, 2019 Share Posted January 21, 2019 I have a 71 240z that has a SBC in it. my valve covers were leaking and cracked so i wanted to replace them but ...the original covers had an oil filler cap hole and two other holes for the breather. Ive looked around for a replacement but found some that they only have 2 holes for the breather and none for the oil cap. Can I use this valve cover and just use one breather and use the other hole to put a cap plug. Do i have to get a cover with 3 holes or can i use the ones with just two with out oil cap hole thanks Quote Link to comment Share on other sites More sharing options...
Miles Posted January 21, 2019 Share Posted January 21, 2019 (edited) All you need is one oil fill hole and one breather hole. Many choices with one screw in cap and one breather. You need to keep at least one breather. Talk to a tech at Summit Racing for advice on the cover and gasket choices. For example: https://www.summitracing.com/parts/edl-4144/overview/make/chevrolet Take your pick: https://www.summitracing.com/search/make/chevrolet/engine-size/5-7l-350/engine-family/chevy-small-block-gen-i?SortBy=BestKeywordMatch&SortOrder=Ascending&keyword=edelbrock valve covers Edited January 21, 2019 by Miles Quote Link to comment Share on other sites More sharing options...
captainkim Posted January 21, 2019 Author Share Posted January 21, 2019 The ones Ive been looking at have two holes but they arent designed for screw in oil cap but ...I "think" an oil plug. Would that work? https://www.amazon.com/SPECIALTIES-POLISHED-ALUMINUM-CHEVROLET-PERMALIGN/dp/B016CKPOKW Also...I have a shorty....but is there any harm in getting a tall valve cover even though i dont need it? thanks!!

LLave Posted January 22, 2019 Share Posted January 22, 2019 I have never seen a SBC crack a valve cover. Interesting. +1 for Summit Racing tech. Hit them up. Speedway motors too! Quote Link to comment Share on other sites More sharing options...
jhm Posted January 26, 2019 Share Posted January 26, 2019 Wow, $300 for valve covers?? Pretty pricey. Regarding tall vs short covers...I used to have tall covers and found they were always in the way of my intake plumbing, etc. Switched to shorts. On the other hand, some short covers may have interference issues with some types of rocker arms. Have been using the Fel-Pro gaskets with steel core and ribbed rubber for years without any leaks. Hope this helps. Quote Link to comment Share on other sites More sharing options...
Miles Posted January 27, 2019 Share Posted January 27, 2019 ++1 Fel-Pro. 9 years since build with no leaks! 1 Quote Link to comment Share on other sites More sharing options...
