Please I need an experts in converting cars from RHD to LHD. There is this RHD Peugeot 407 that was sent from UK and needed to be converted to LHD.

Please, where and How much will the conversion cost me?

Thanks

Lejuen, I respect your advice and realise there are considerations unique to Nigeria I probably am ignorant about.

Seeing you working on an A4 confirms what I already presumed you are not parochially restricted in your applicable knowledge and experience to strictly one brand.

I want to buy an Audi Q7 TDI to use in Nigeria however the L3/4 my other option is considerably more robust off road. However, I believe in fact I know, the build quality of the Audi is considerably better than the L3/4. The long term outcomes for the Audi Q7 could mean better resilience, reliability and therefore toughness. However, all of this will amount to nothing without good maintenance from a good conversant mechanic like you.

I prefer the Audi, better drive much more compliant ride on the bumpy roads, I will be doing about 5000 miles a year if that from 2/3 trips to Nigeria and I will be driving Lagos to Delta (Warri-PH) but mainly resident in Lekki.

What’s your advice please Sir ? Not worried about TDI engine issues in Nigeria with you around.

Failed head gaskets are the most common reason for combustion gases getting into the coolant. But it’s important to understand that you can’t fix a head gasket failure by just slapping on a new gasket and bolting it together. Doing so will usually result in a repeat failure at some future date. You need to find and fix the underlying problem. That means repairing mating surfaces that are not perfectly flat, repairing the cause of the pre-ignition, or fixing the cause of localized overheating. Localized overheating is often a result of injector or ignition troubles on one cylinder and it can be difficult to find but it’s an insidious killer. Left alone it will overheat a single cylinder until the liner loosens in the block and even greater damage ensues.

The heads are checked for flatness with a straightedge. Aluminum heads should be flat within .002 inch. They are checked for cracks by applying air pressure while bolted to a jig, or by application of liquid crack detection chemicals that highlight cracks under black light. Cracked heads can usually be repaired by welding. Warped heads can be surfaced on a milling machine or specialized cutter. Rover heads should not be surfaced more than five thousandths of an inch, because the compression ratio increases as the heads are shaved.

If coolant was entering the combustion chamber you will see one or more cylinders scoured spotlessly clean by the steam. Pay particular attention to those cylinders if you see them because they are the ones that have failed. If you see this, or if you see milky oil in the engine, you should pull the oil pan and check for lower end damage because coolant is getting into the oil. Coolant mixed with oil will damage bearings.

The steel cylinder liners are pressed into the block and milled flush with the top. If you see any liners that have moved downward that’s s a sure sign of failure. If you do not see any signs of movement in the liners you must make a decision to remove and test the block or take your chances and refit the heads.

The block is tested by bolting plates over the cylinder head mating surfaces and applying pressure to the oil and coolant galleries to check for leaks. Leakage indicates a loose liner or the presence of a crack.

The block can also be checked for flatness on the cylinder head mating surface. As with the head, the surface must be flat within .002 inch. I have seen a number of instances where shops replaced head gaskets, experienced a subsequent failure, and assumed the block had a bad liner when in fact the deck surface was warped. It’s important to figure out what went wrong if you are to have a lasting repair.

A block with a dropped liner can be repaired by removing the liner and pressing in a slightly larger replacement that is flanged at the top so it can’t move. A block whose cylinder head mating surfaces have warped can be surfaced in a process called decking. If the cylinder head mating surface has warped, there is a good chance the crankshaft bore is warped also. In that case, the block will need the main bearing journals line bored after it’s been decked.

The traditional method of fixing liner and deck problems in Rovers was to replace the engine block. With the increased costs for new blocks repair is now becoming a better option.

I hope the tips in the article above will allow you to diagnose your overheating trouble. In the case of engines with combustion gases in the coolant there is usually some other problem that led to the internal engine failure. Before you count the job done you should find that problem and fix it.

Finding those problems — things that cause internal engine failures - will be the subject of a future article.
