Probably not if the one with the blown head gasket ran the other engine should to .
Make sure the engines are compatibule if so you missed something when hooking it up dubble check your wireing and connections .
Its likely something simple stand back look at it from a different prospetive their is a lot to do and think about when installing new engines in a short peroid time its in look at from a different angle .

SOURCE: blown head gasket

Look the engine over and see if you can find any external leaks, change the thermostat and make sure that fan(s) are operating.
Check the oil for water...loosing that much, it has to show up somewhere. Blown headgasket usually puts oil in coolant or coolant in oil, causes an external leak from between head and block or goes out through the tailpipe as steam.
look carefully and you will find your problem!!

SOURCE: 1992 toyota camry shaking very bad could this be a

Hi,

When a cylinder is misfiring, this dirupts the balance of the engine and the computer is sometimes unable to compensate during a misfire.

This also, can often cause erratic engine behaviour...and shaking like a tank.

It may simply be a bad spark plug, HT lead, or something more serious.

Have the onboard diagnostics checked first - this will indicate which (if any) electrical component is at fault.

This can be done by a local Toyota dealership, with the correct scanning equipment.

We think that it stopped running due to no fuel. the engine ran rough ever since. Seems to be flooding to the point that fuel was getting into the oil in the sump. Running rough ever since.


Get a cylinder compression test done to check head gasket and to check head is not warped or cracked.
if head gasket or head problem = one cylinder may be affected causing fuel could get into the oil via a blown head gasket. if one cylinder not firing it would run rough.

Has the engine been over heated recently ?

Need to remove valve cover on 2000 Camry Toyota


For the four cylinder engine:

  1. Remove and label all electrical wiring, connectors and vacuum hoses necessary to gain removal clearance.
  2. Remove the spark plug wires. Disconnect the PCV hose.
  3. Remove the four nuts and grommets located on top of the cylinder head cover.
  1. Remove the cylinder head cover and the cover gasket from the cylinder head.
  2. Discard the gasket and replace with a new one.
To install:
  1. With a wire brush or gasket scraper, remove all the old gasket material from the cylinder head and the cylinder head cover gasket surfaces.
  2. When the cylinder head surfaces are free and clean, apply beads of sealant to the cylinder head in the locations shown in the accompanying illustrations.
  3. Install the new cylinder head gasket in the cover. Make sure that the gasket seats evenly.
  4. Place the cylinder head cover with the gasket onto the cylinder head.
  5. Install the four grommets and nuts. Uniformly tighten the nuts in several passes to 17 ft. lbs. (23 Nm).
  6. Connect the PCV hose. Connect all removed vacuum hoses, connectors and electrical wiring. Connect the negative battery cable.
  7. Start the engine and inspect for oil leaks.
  8. Repair any leaks as necessary.

Engine coolant level drops on Mercedes C180 2001 model


Loss of coolant is serious because if you allow your engine to overheat you can cause very expensive engine damage - thousands of dollars of damage (not hundreds).

The items that need looking at are:

- Radiator cap is old and faulty. This can allow coolant to escape and needs to be replaced every 4 or 5 years (sometimes sooner) with the correct spec cap - not any old product picked up at some auto store.

- External leak - you need to check all flexible coolant hoses and connections for leaks as well as around the water pump to ensure the WP gasket is not leaking

- Internal leak
The most common is a blown cylinder head gasket which can allow coolant to escape and to get into the cylinders and into the lubrication system. If getting into the cylinders you will see white smoke coming from the exhaust . You need to check the engine oil for coolant contamination as a coolant can escape into the lubrication system via a damaged head gasket. You also need to check the coolant for signs of oil escaping under pressure via the blown head gasket into the cooling system.

An internal leak can also be caused by a cracked cylinder head but if you have this condition are blown head gasket will have probably occurred around the same time.

CYLINDER 3 MISFIRE YARIS


Remove the spark plug of cylinder No. 3 and inspect it for any water or coolant traces on it. If water droplets are found, the gasket is at fault and need replacement. If not, the gasket is fine and does not need any replacement. It is recommended to check the valve clearance before entering into major repair.

My motor runs very rough even with new spark plugs,, is there anything else I should check? and is it common for a headgasket to leak at 107 000km?


if the engine runs rough after spark plug replacement,you may have a clogged fuel injector perhaps. i would suggest that you purchase lucas fuel injector cleaner and add it to your gas. you may have also just bought some bad gas. if you suspect that, just add 1 bottle of clear rubbing alcohol{not green} clear rubbing alcohol to your gas tank.this will dry up any water thats in your fuel.it will not affect the engine at all. as for your head gasket,its something you cannot predict any mileage on,but you can prevent it by not letting your engine overheat. never run your engine hot. always keep your collant full.if you suspect a blown head gasket, here are some signs of a blown head gasket. oil in the coolant,coolant mixed in your engine oil{when you pull the engine dipstick out,it appears muddy looking,coolant coming out of your exhaust pipe.these are quite a few examples of a blown head gasket. hope this helps and thank you for choosing fixya.com

It wont start after oil spill


This could be as simple as damaged spark plug wires (due to oil spray) or as serious as burnt valves or blown head gasket. I would first clean the engine bay of all oil residue. If the ignition wires seem to be sticky or melty even after cleaning, they are probably bad. You can confirm this by watching the engine in a dark garage while someone else turns the key. Make sure you oil is at the correct level. If you see sparks jumping from the wires to the engine block or valve cover, they are bad. Another test to do is compression. You can rent a tool for this at most auto part stores. Check the compression on each cylinder, again making sure the oil level is correct. If one or more cylinder reads very low, you probably have a burnt valve or a head gasket leak. If all cylinders are about the same, but the pressure is low, the piston rings may have been ruined. You can pour a small amount of oil (1-2 tbsp) into each cylinder through the spark plug hole and retest. If the pressure reading increases substantially, the rings are bad. If not, the.head gasket has probably failed. Assuming that the oil never ran out and the engine never overheated, however, the main problem is probably in the ignition. A tuneup with new spark plugs, wires, distributor cap and rotor may solve the problem completely.

No power, overheating


Hello and this is a blown head gasket from what it sounds like. I would check your oil and if it looks grey or milky you definetly have a blown head gasket. You can check for a system leak with a compression system tool from your local auto parts store but make sure to check your systems max pressure before installing the tool. I am read sure this is a head gasket. If you have any other questions email me and I hope you have good luck in fixing this problem.

Overheating and water mixed in with oil


Absolutely correct. Have cylinder head dye tested and checked for warpage before re-using. Do not run the engine any more than necessary ( into the garage or onto flatbed on it's way to shop) or you risk doing damage to engine bearings.
