@Gazzuzz please can you recommend any locally available high temperature grease that can be used on brake calipers? I fear to use a brand that would degrade rubber boots. Need to lube my caliper pins.

I'm using synthetic base greese for caliper pins and it's works just fine.

DO NOT use copper greese cos after some time it will block pins !

You do complimentary full tank of fuel too??

Abeg, I dey bring my car tomorrow!!

It's optional and factored into your bill.

Fuel tank down, fuep pump out.

O2 sensors located and removed, B1S1/B2S1

Network is really bad

O2 sensors down

New fuel pump, ford expedition and fuel filter to go with it.

Kia Rio parts

Many thanks. Do you have a name and where did you get it? Sorry Gazzuzz for derailing

This is a special greese for brakes pins TRW PFG 110

Ford explorer 2004

Fuel pump pressure test without installing gives a almost 5bars , didn't know the v8 used so much pressure. Well in contrast to 2bar/1.5bar that is settled

With fuel tank still on the floor and fuel pump installed car is started and revs well, but rough idles, a quick spark plug change, o2 sensor replacement and injectoer service in the morning, and this baby is out of here



P.s warning, never connect your fuel pressure tester directly to a fuel pump, its best connected in series with the pressure release valve.

The Kia gearbox is down.

Clutch plate is being installed

Notice the clutch aligning tool? Never leave home without one

The Nissan xterra

Small leak noticed at the top of radiator, there's a crack at the top, probably caused by old age.

No cause for alarm, no need to replace entire radiator, just the top will be replaced in the morning.

I could not document the coupling of the v6 camry, cause it was done late at night and battery was flat, but it's gone and owner is happy.



Funnels I bought in traffic.

Ford expedition 2004 4.6liter engine

Sparkplug change underway

Tools that would be of help pic below.

A magnet is also very important

Ford Expedition

Plugs replaced, injectors cleaned, o2 sensors changed.

Car still rough idles and there's hesitation before take off, ordered for an MAF (airflow meter), waiting for delivery. Weather has not been friendly with my suppliers.

Nissan Xterra radiator top removed and replaced. The process is very kazeemy so I skipped pictures


Job complete car should leave today.

Kia Rio 07, suspension and clutch work complete, drives really smooth now.

Job complete pending a complete wash.

Ford expedition 2004

Got really stumped on the rough idling and hesitation on the 4.6liter v8 engine, and decided to leave it for a day to research some more.

I totally ignored the rattling noise the engine made and felt it was engine wear until I read this article.

Also I noticed oil was non existent on the dip stick when I checked and had to inform the owner.



It totally explained the rattling and rough idling

In 1991 Ford Motor Company introduced their first modular V-8 engine. This was for the 1991 Lincoln Town Car and the cylinder displacement was 4.6 liters. The engine is popular and is produced in a number of displacements. They also build two, three and four-valve per cylinder versions with different cylinder heads

The Ford 4.6 liter and 5.4 liter engines power millions of SUV, truck and car models. The Ford Modular engine is well engineered, but it is designed for specific lubrication. The oil viscosity and the type of oil filter can mean the difference between reliable service and an expensive repair.

Why the proper oil is so important

The modular engine is an overhead cam design. Two very long timing chains keep the camshafts in time with the crankshaft. Because of the length of the chains, guides are needed to reduce movement. They also use a hydraulic tensioner to keep each chain tight. Oil pressure moves the tensioner which controls slack in the timing chains. These components rely heavily on proper lubrication from the engine’s oil.

Ford originally specified a 5W30 motor oil for the engine. They soon found this caused oil consumption and possible catalytic converter problems. This caused a change in the specification to a 5W20 or a 5W20 synthetic blend. It is also believed the lower viscosity oil can travel to the timing chain tensioners more quickly. The oil filter they designed for the engine also has a specific anti drain-back valve and for good reason.

The anti drain-back oil filter

With a substandard oil filter the engine oil may drain back to the oil pan when the engine is turned off. A lack of oil pressure means the tensioners cannot immediately tighten the timing chains on startup. When this occurs, slack in the chain tends to jerk and the plastic timing chain guides can break.

The problem of broken guides on the timing-chain

We see many Ford modular engines with broken timing chain guides. The first symptom is usually a rattle on the start up. Because the timing chains are so long, they are supported by plastic guides. The timing chain is kept tight by force from the hydraulic tensioners. With the proper lubrication and the right oil filter this works very well for a great many miles. Problems begin when improper viscosity oil and substandard oil filters are used.

With a substandard oil filter the engine oil may drain back to the oil pan when the engine is turned off.  A lack of oil pressure means tensioners cannot immediately tighten the timing chains on startup.  When this occurs slack in the chain tends to jerk and the plastic timing chain guides can break.

　

Symptoms of a broken timing chain guide can range from a rattle noise on startup (not always) to rough idle to a check engine light.  This engine was fitted with the proper Motorcraft filter after the noise started.  Unfortunately it was too late to prevent an expensive repair.  The guide on the left bank is broken and the check engine light has come on.




A broken chain guide is apparent, once removed and compared with a new part.  The guide most often breaks where the mounting bushing passes through.  This allows the chain to drop down and often it starts to rattle, until the tensioner removes the slack.





When the timing chain guide (1) breaks, the chain drops down.  The chain tensioner (2) attempts to take up the excess slack in the timing chain.  When the tensioner piston extends, the chain is pulled tight. Removing this slack on one side of the chain also causes the cam sprocket (3) to rotate and change camshaft timing on that bank.


 

Rotating one cam sprocket disturbs valve timing relative to the other side of the engine. This can cause a rough idle can set diagnostic trouble code (DTC) P0300 and codes for lean and rich operation. Many times these engines come to us, after having been mis-diagnosed elsewhere.  Needless part replacement has often been a further waste of money. Repair involves timing cover removal and replacement of the chains, guides, tensioners, etc.  Changing to the proper oil viscosity and a Motorcraft oil filter, prevents an expensive repeat of the problem.

Replacing the timing chains

To replace the chains and guides, we must be certain to align the camshafts and crankshaft. If valve timing is not properly set, the valves may hit the pistons and cause severe engine damage. Timing a Ford modular engine is not a simple task. Articles on the internet state, not turning the camshafts or crankshaft allows replacing the chains without timing the engine. This is very dangerous at best and may cost an engine. It also fails to recognize cam timing is already off when a guide breaks.

Will have to inform owner on new developments before continuing the job.

Salute Gazzuzz, I 've been silently following your thread and I appreciate it. I have a Lexus rx330 2005, when I bought it I noticed that when I turn on the ignition the fan starts working and when i asked the dealer, he told me when the vehicle was brought in the a/c didn't work and they had to connect the wire directly into the compressor and creating a relay for it. I saw all these myself. A saw pin wire that is supposed to be attached to the fan junction hanging and when I put it in the fan stops working and a/c releases gases as if it's overfilled. I have attached pictures. Please how can I get my ac to be working just the way factory made it. Thank you.
