Toyota 76/78/79/200 1VD Dusted Engines Group Australia has 6,341 members. de-rate the engine shut down the engine. Badly leaking charge air cooler, cracked exhaust manifold AND dusted engine!!! Valves look OK but the cylinders are glazed... almost polished. It should be less then 8 " hg at 3000 rpm with 0 load on the engine. This was determined by 2 elements. Which engine system would the technician inspect to detect and repair the fault? Again, thanks for the conversation this morning, it was very helpful, and I … A technician has been instructed to diagnose the cause of a dusted engine. This can happen if sensors stop functioning properly because of carbon build-up or if build-up keeps the intake valve from closing properly. Under test, care was taken to aSsimilate road conditions. I find it hard to believe that these diesel engines are so delicate that a little dust introduced into the system when the air cleaner is changed will cause them to die. Intake system. First, the engine will lose power. High air intake temperatures may _____. Put by Mr. P. H. Moore, of Messrs. Moore and Barrett's • research laboratories, Whyteleafe, Surrey, have shown that efficient air and oil filtration considerably prolongs the life_of an engine. And should always be tested cold. This can make the engine … I read some posts that talked about "dusting" as a cause of engine failure. One dust was found in the duct work coming off the back of the air filter module. The last thing, I believe you stated that if the engine had been dusted because of a faulty air filter there is no way that would cause the rings to break on the #1 and #2 cylinders. One of the main problems carbon build-up does is to change the ratio of fuel to air in the engine. This is normally caused by a aftermarket (K and N) air filter. Two the blow by test was 3.5". What exactly is engine dusting, what damage does it do and what can you do about it if you already own a late-model Toyota 4WD? A ducted fan is an air moving arrangement whereby a mechanical fan, which is a type of propeller, is mounted within a cylindrical shroud or duct.The duct reduces losses in thrust from the tips of the propeller blades, and varying the cross-section of the duct allows the designer to advantageously affect the velocity and pressure of the airflow according to Bernoulli's principle. Engine was dusted, smoking and burning oil. The vanes get worn by the dirt entering the air inlet. The first sign of a dusted engine is the turbo. Ring end gap is double what spec is and the cylinders measure .030" over spec. Engine dusting have several characteristics to watch for when assessing a concern and affect all moving parts in the engine. The ingress of dirt allows for the piston ring to be worn on the running surfaces and edges, so they can no longer seal the cylinder sufficiently and can therefore no longer prevent oil from passing into the combustion chamber. ExTENSIVE engine tests carried. Okay, so dusting is the generic term for airborne dust entering the engine when it should have been stopped by the air filter. The test that you are probably refering to is the crankcase pressure test. Now the max spec on this engine is 12". Therefore I was not comfortable that I really had a problem. This page is for anyone who has experienced dust ingress past the factory air filter on a 1VD-FTV powered Toyota Landcruiser.
