Water leaking where hoses join engine block

The water hose connects to a plastic section that slots into the inlet manifold. This then relies on a rectangular shaped rubber gasket to seal against the engine block but can easily leak so a good idea is to add some silicone gasket sealant before tightening the inlet manifold nuts and the 2 bolts that hold the water section of the manifold

Car has delayed reaction time when I push the accellerator on the highway. 2. car shuts off at stops signs and red lights

There's a few possible causes which include blocked air filter or fuel filter as well as a clogged-up fuel injector.

Also consider an air leak - air being drawn into the injection system somewhere (or via a gasket on the inlet manifold). To check for an air leak, start the car and spray a light penetrating oil such as WD40 around the inlet manifold and pipework (including flexible rubber connectors) on the fuel system.

If air is being drawn in somewhere it shouldn't be, you may well get a cloud of whitish-blue smoke from the exhaust as the penetrating oil is also sucked in and burnt

Re: 98' Honda Accord V6 with DTC P0442, the smog check tech said, that to repair this problem I would need to find a mechanic that has a smog pump in order to find where the problem is occuring fr

it basicly means you have got an air leak on your inlet manifold or one of the pipes or hoeses going to the inlet manifold or even the manifold gasket.
if you start the car up end listen under the bonnet you may be able to hear and locate the leak

if this helps let me know

2002 focus engine light on, code po171, whats that?

Lean operation, usually caused by a vacuum leak. Check all vacuum hoses for looseness or cranks, etc. Also check the main air inlet hose from the air cleaner for tears. If no vacuum hose leaks, check the intake manifold gaskets for leaks by spraying carb cleaner on the gaskets while the engine is idling. If the speed changes when you spray the gasket, it is leaking.
If all that is good, try cleaning the mass airflow sensor by spraying electrical parts cleaner on the wire of the sensor. Please let me know if you have questions, and thanks for using FixYa.

I have a 2.5 v6 ford telstar 1992 theres an air leak comming from somewhere and its missing and wont idle at all.I took the air filter system and air flow metre off and now it idles really high but can...

the most likely cause is a damaged vacuum pipe between the inlet manifold, and the brake servo unit.
this would account for the missing and idling, due to the extra air getting into the engine.
it will also account for the brake hardness as there will be no vacuum to the servo unit.

the pipe is probably between 1/2" and 3/4" diameter and go from the inlet manifold to the brake servo unit on the bulkhead. make sure this pipe is not split or damaged and it is connected securely at both ends.

it is possible that the manifold gasket is leaking, but it would be very unusual for this to happen unless the manifold has been disturbed

Car keeps dying when giving gas, idles low, dies at stoplights and stop signs

Problem could be either to much air OR to much fuel in inlet manifold
If you have a pipe broken or come off the inlet manifold from either a breather from the engine that could cause it, or a problem from the fuel tank such as a fuel filter on the line from the tank to the engine,or Air Filter needs cleaning etc, or even a air leak in the Inlet manifold gasket.

I have a hard time starting my car. When it does start the idle is eratic and it idles at 1500-2000 rpms. ive been told its a vacume leak. Which lines should i check first? What else could it be?

For a vacuum leak,you should check all those little rubber vacuum hoses that are used for pollution control, as well as the larger rubber hose that goes to the brake booster from the inlet manifold. They tend to go hard and / or split where they connect to the metal piping if they are over 10 years old, allowing air / vacuum leaks into the inlet manifold which upsets the idle mixture causing rough / uneven idling. If the hose is long enough you could trim about 1/2 inch off the end and re-attach but if the hose is hard and brittle the best option is to replace any suspect hoses completely. Most auto parts retailers sell the hoses cut to any length you need. Also check the clamps on the large tubing that runs from the Air Cleaner Box to the Inlet Manifold to ensure that they are tight and not allowing excess air into the system that is not monitored by the Air Flow Sensor.
The other possibility for a vacuum leak is where the inlet manifold joins to the engine head. To test for leaks, squirt a little oil on the junction to see if the idle changes. If the oil test gives an improvement, then the manifold gasket will have to be replaced as it is probably split or the face of the manifold is not true and conequently not providing a flush joint.

check for leaky intake manifold gasket. I spray carb cleaner all along the gasket with engine running. If the engine speed changes, there is vacuum leak.

Error code says it is running lean. I replaced the air filter and cleaned the sensor. what other possibilities?

Air/Fuel flow mixture screw needs altering as mix is too lean and will keep causing problems.

92 gmc 350 pickup....rough idle..have replaced MAP sensor, fuel filter,PCV valve, and idle control on throttle body...still having the problem

This could be a couple of things:
  1. Check that you have not got any vacum leaks between inlet manifold and cylinder head.
  2. Check your spark plugs and HT leads are in good condition and not worn, reset gaps. If worn replace them.
Worse scenario is the head gasket make be leaking water into a cylinder. Get a cylinder leakage test done to verify any manifold air leaks or faulty sealing head gaskets.
Good luck, let me know how you get on.
