poor pick-up and less miles per gallon after engine head repaired is due to two things could be done wrong during repair,
1: wrong tappets clearance, witch is suppose to be 0.30 MM inlet, 0.40 MM exhaust
2. wrong timing setting ( timing belt setting )
better to get your mechanics to double check it
good luck
It is the valve adjustment.The engine requires tuning which can be done by a professional auto mechanic. Please get it done as soon as possible to avoid fuel wastage and efficiency.
Hello smileynv: My name is Roger and I will answer for you.The 1988 Pontiac Firebird had a 2.8 v-6 engine. The timing set at 10 degrees in drive. The 1989 pontiac Firebird has both the 2.8 and a 3.8 engine.The 3.8 engine a DIS (direct ignition system) Had no distributor. The timing was preset and controlled by the computer system. There was no way to adjust the timing. Please rate the answer. This way I know it was useful. Should you need further help please just ask. Thank You for using Fix Ya. Roger
The electronics for the timing is all electronic coming from the engines computer. If you had rebuilt the entire engine you just assemble it correctly and the computer does the rest
whyknot87: As far as I know, Nissan did not put a 2400 in a Sentra in 1992 or for that matter any year that I am aware of.
The Sentra had an SR20DE Which was a dual overhead cam engine.
According to Nissan, setting the timing on this engine requires the use of a scan tool as part of the procedure. There is no procedure for setting it without a scann tool.
The timing for this engine is 15 dedrees +/- 2 degrees @700RPM
The other engine this year Sentra used was a GA16DE
which was also a dual overhead cam engine.
This one could be set in a conventional manner with a regular timing light. You must have the engine at normal operating temp.
Disconnect the throttle switch and then you set the timing to
10 degrees +/_ 2 degrees @700RPM
The 2400 engine you probably are referring to is the KA24DE which came in Nissan 240SX and the Nissan Stanza. There are procedures for setting these as well, however I need to know wha4t car and engine you have?
The 2400 had 15 degrees +/- 2 degrees @700RPM
unplug the relay it should have a black and a tan set of wires, it could be on the fire wall or by te distributor, mark your timing marks on the vibration damperand the timing cover your correct timing setting should be on a sticker under the hood. hook up your timing lite to # 1 cylinder and adjust away. if you need more info let me know.
Before you set engine timing i recomend that you check for trouble codes. You can do this by jumping TE1 and E1 whitch on your engine is a round 2 wire plug on the drivers side, by air box. if you have a code then have the problem fixed, because some codes will effect engine timing. You must have the TE1 and E1 jumped when timing engine. The engine timing marks are on the oil pump on the front of the engine,down by the crankshaft. Timing is set to 5 degrees advanced(factory). Also make sure you have no vacum leaks they will also effect engine idle 900rpm which is the setting for setting the timing at.
Picture of TE1 and E1
Also make sure your engine distributer cap is good and same for plugs and wires. I hoped this helped.
Also timing chain strech which will affect timing.
