Question about Cars & Trucks

1 Answer

I have a 1988 ford F150 4.9L VIN code (Y) .I had a bad head gasket and a bad head so i replaced both of them. Now that everything is back together i can get the engine to crank but not fire over.

I have fuel from the pump to the filter, and from the filter to the injecters. I also have plenty of spark comint from the coil pack to the cap wires and plugs; but it will not run. So i had determined that it might have been because the timing was off.So i took everything back off to check thew intake valve for the #1 cylinder and it was opened when the crank was at TOP DEAD CENTER (TDC). So i then took the distributor cap off and look at where the rotor was positioned at while the #1 piston was at TDC. However the rotor was positioned at # 4 wire. So i took the distributor out and placed it according to the # 1 SPARK PLUG WIRE on the distributor cap, then sat it back in place flush with the engine block and the engine back together after i saw the injecters sqirting gas. Now that everything is back together i still am not having the engine fire over!!!!!!!!!!!! WTF

I would suggest that you have incorrectly timed the engine.The proper way is to set number one cylinder to top dead centre on the compression stroke, if you look at the harmonic balancer on the front of the engine you should see a groove that marked top dead centre.With the engine at set at top dead centre take the distributed out of its mounting.
with the cap removed, you should find a small market on the top face of the distributor body.
This might only be a small mark but it is on the flange where the cap normally sits.
When you insert the distributor the mark on that distributor casing should line up with the distributor rotor button. You may have to remove the distributor slightly so that you can line up the rotor a button.
You may in fact have to do this two or three times until you get the marks lined up.
Then check the firing order of your engine, this is normally marked somewhere on the engine.
Once you have done this you should find the engine will start, you may have to adjust the advance on the distrubor to 4 to 12 degrees before TDC with a timing light.

07 suzuki reno vin #kl5jd66z37k643089 replaced the head gasket put together now it will not start no fuel press. or ignition spark

in usa this engine is L34 or U20SED
i guess you are working with no scan tool????
that be super hard, to out guess the EFI system.
we cant see electrons so.. tools make the man.
DOHC engine
if there is no spark times 4, did you check all 4?
After all 1 cylinder or all 4 can fail. telling the
mechanic big clues
if sparks ok test fuel works (sprayed).
is the timing belt under 60,000 miles new?
if the belt slips compression x4 drops radically.

head off, well i think this is an interference engine.
its DOHC, so if you bent the valves by driving until the belt slipped, oops, you killled the head.

funny thing is no history here
am I to guess, engine died? and the head was removed
was the head tested, when off?
new head, rebuilt head,
check for warp
and do the valve test with I use kerosene
in the combustion chamber to see if the valves are not bent, if bent the fluid leaks to the ports.
oldest test on earth this, 100 years. old.
and more, take it to a machine shop (head)
and get it pressure tested, etc>> now that be savvy.

Do i need to have my 2004 dodge intrepid anti theft code reset through a dealership if the heads and head gaskets were replaced? the entire top of the engine ws taken apart adn put abcl together.

i would disconnect the battery. removing both the positive and negative battery terminals. with both ends disconnected, hold the two terminals together for about 10 seconds. this will proform a hard reset on most chrysler vehicles. also, if this doesnt work, try turning the key to the on position, and then proforming the hard reset procedure.

I have motor oil going into antifreez what could that be

Blown head gasket.
Repair entails getting the cylinder head removed(which means pretty much everything you see when opening the hood), buying a replacement head gasket, resurface the cylinder head and bolt everything back together. You could do this yourself since this job does not require a rocket scientist, just someone with attention to detail and not afraid to get his/her hands dirty.

Blown head gasket

Depending on the size of the leak theragasket may work. There are other products that add to the anti-freeze, if it's anti-freeze that is leaking. Some add to the oil. For a temp fix I would and have been able to prolong a head gasket replacement. But it's just a temporary fix. Could last 1 week, 6 months or not at all.
A head gasket replacement is not a easy job, messy if you do it and a little costly if a shop does it. I've been there, Good luck
