When i first start my 1.5 single over head cam civic the vtec works but when the car heats up the vtec stops working. i have changed all the oil filters and replaced the solenoid but it still wont work properly. What do i do?
More than likely its your temp sensor on the front of the engine, Ive seen it be the cause of things similar including high idle when car first starts(happened to me when I switched out my 1.5 for 1.6 sohc vtec engine, engine was built as an automatic so i changed out the flywheel etc but no place for the sensor) and happens to be the sensor for my radiator at the same time so it controls the fan.

It is quite simple to replace the VTEC Solenoid assembly. It is located on the rear right upper side of cylinder head (right side with reference with if sitting if driver's seat) on the intake side. It is attached to the head by means of 6mm bolts. Just remove the connector (NOTE: It my have single VTEC solnoid or two, depending on the model), remove the bolts and take out the solenoid. Please see the diagram:
After so many over heats.a car sometimes cant handle. after constant over heating your cars rubber gaskets could have gone bad and turned brittle letting in oil into spark plug well #1 for your spark plug problem i would recommend changing your valve cover gaskets. and for the over heating and not turning on. i believe you blew a head gasket.
The Head bolts are located below the cams, so you have to take the cams out to get to the bolts.
The torque specs for the head bolts in sequence is 20, 40, then end at 63ft lbs. Be sure to apply anti sieze or dip the head bolts in oil, before you torque them down or you might pull out the threads. (Not a good thing TRUST ME!)
Hope this helps.
The 1996 civic has a 1.6L b-16 engine. The only difference between the v-tec and non v-tec engine is the dual overhead cam i believe. The 93 civic also should have a b-16 engine in it. The cylinder head should work.......
well its about what you want the single cams can rev high...the 2nd fastest world record is in a turbod d16 ...202mph for a single cam civic..the b16 has more dynamics in the high end of boosting... the b16 aftermarket is stronger but they **** on the low end of the rpm gauge..
the best motor is the b20 crv block its 500 bucks you can vtec it with a b16 head and run big loads of turbo and get to the 10 sec class of things...if you go to b series you will need to change the ecu to hondata and you should look for ls integra trannys...next the axles ...I reccomend B20 its a harder build but its worth it and youll spend 1000 less than an gsr or prelude motor...google the b20 dart motor with ITBS you will see!!!!!!!!
hi you will know if it works it don,t kick in till the engine reachs a certain rev range usually around 3000 rpm then it transferes to the hi lift cam and when it kicks in will feel like a turbos been fitted. if not you have a problem with it which would likley be a problem with its solenoid or oil pressure. yates210456
