My number one and number four cylinder is not firing there were two cracks on one and four of the distributor cover but they were stick with poxy steel glue could the crack still be a problem in loosing current because the the valve is still not firing also burning oil and have a miss in the idiling not smoothidiling
Pull the spark plug wires out of the number one and number 4 cylinders, then pull the spark plugs out aswell and connect them to the wires they go to. then hold them two the engine block and see if you have a good strong spar/ark.......if not then ur distribortor crack is ur problem, if it does spark take all 4 spark plugs out of the engine and hook up a compression guage and check the compression, if good then check the fuel systesm, fuel pressure regulator/fuel injector/most likely not the fuel pump....if compression is bad then pour a tea spoon of oil in the cylinder that has low compression, do the compression test on that cylinder again, if the initial low reading goes up then its ur piston rings or ur cylinder wall, if it stays the same then its ur valve seals,valve guid,vlave seat carbon build up, check valve train may need a head job

If the firing order is "1-3-4-2". First put it no.1 piston TOP DEAD CENTER. with the marks aligned. Adjust valve lash according to spec on intake and exhaust. Then turn crankshaft on whatever rotation it is suppose to go eg counter clockwise etc. quarter turn ( four cylinder engine). then adjust number 3 ( firing order 1-3-4-2). Then do the same for cylinder 4 and 2.
Hello: Sir, the 301 is telling you that you have a mis-fire on cylinder #3, You may have a bad spark plug, or bad wire going to #3 plug or you may have a ignition unit that is not firing #3 cylinder, With the #3 cylinder not firing it caused the 420 code that means the catalytic converter to be below acceptableefficiency for emission standards. Repair the 301 before you replace the converter
did you continue to crank it to start ?
did you hear anything other than usual starter noise ?
you may have gotten lucky if no clanking or clicking noise ---don't try to start it again though
and that is timing belt not camshaft
for future knowledge when considering a vehicle for purchase ---ASK or find out if it's what's called an interference motor or the non interference design ---if you snap the belt on an interference design
alot of twin cams are --but I see a trend from automakers to get away from this --which they should
then albeit some or even major damage can occur ---the 91's civics 1,6 Single over head cam is a non interfernce design --now 1989 or 1992 on well that's another matter
I love my wifes 1991 civic dx ---to date only things ever to fail was the distributor and the timing belt and tensioner ---ps --think about replacing the water pump --front crankshaft seal as well while
you are in there replacing the timing belt ---do a coolant leak down test too --= 5 minutes
to check intake gaskets etc and head gasket --opportune time for a replacement
Yoy can buy the entire engine gasket set generally cheaper that a few individual one and keep
the others for future or give them to a new owner Someday --good 1 st cars --they are capable of 250,000 + easy ---key to longevity ---add an oil cooler with cooling fan set at the right temp with
fan --even better if you live in the mtns like I do
My sincere apologies for the extremely delayed response. I am personally going back to answer your unanswered questions. I have only been a free contributor to this site for the past 4-months.
I do not know if you still need this information, but I am going ahead and answering it anyway.
1. Non Turbo =VG30E. Turbo = VG30ET. In any case the Engine Cylinder numbers, Firing Order, and Distributor Connections are the same.
For the 3.0L: Firing Order: 1-2-3-4-5-6 Cylinders: (back of engine) 5--------6 3--------4 1--------2 (front of engine) Distributor:
....(back) .6......5......4 .|.......|........| V......V......V |..................| |..................| ^.......^.......^ .|........|........| 1.......2.......3
2. I am not sure what what "cam adjustments" you were looking for. I am sure you probably have taken care of that or found what you were looking for. However, in most cases the person is really asking about the Timing issue.

depends on engine code, and single cam or twin cam. check your code. D16W4 sohc stage 1. 29nm stage 2 72nm. D16Y5. stage 1 20nm. 2. 49nm. 3.67nm . 4. 67nm. there are 2 other codes for sohc engines these are the same as D16W4. DOHC engine as follows B16A2 stage 1. 29nm. 2. 83nm. hope this helps, if you are ot sure give m the exact engine code and i can verify.
