I'm excited to announce that thejdm is now updated to the latest phpbb 3.2 software. You may notice the site is now mobile friendly but with the upgrade comes some hiccups. theGarage, theGallery, theArcade are no longer supported. In due time the developers should be working to release the modifications to work on the new software. #LetsMakeForumsGreatAgain

LS Vtec

Post by Builtb18b1 » September 02, 2009

I built an LS Vtec in march of 2008 using a b18b1 bottom end and a b18c1 top end. Until now I have had no problems with anything. Then last saturday night i was crusing in 5th gear and it just suddenly lacked pewer. It still runs but it misses real bad. I took the valve cover off and checked the cams and timing and everything seems fine. Does anyone have any suggestions?

I would check distributor cap, rotor, and plug wires. Just to rule that out too.

I did a compression check today and cylinders 1,3,4 are fine and cylinder 2 had no compression what so ever.

I'm doing some research on valvetrain. Does anyone have any suggestions or recomendations on which company to go with? Right now I'm looking into crower and skunk2.

Why not just do a Type R valvetrain?
