Hi to All, I am in the process of rebuilding a 200tdi defender engine I recently purchased. After inspecting the cylinder head I noticed some marks next to the valves as shown in the pictures. Does anyone know what is this and what caused it? Do I ignore it or more attention is needed? Thanks in advance!!
I'm of the opinion that the cylinder head on my tdi 200 isn't in the best of health, worn valve guides and the like, etc and was thinking of getting it reconditioned. The two serious reconditioners, Turners and ACR, both have a "performance" version of the head for not a lot more money. Has anyone fitted one of these heads? What was the experience before and after? I'm just wondering if it's worth it? G.
I've asked this question on another forum but nobody can answer it. I understand that a 300tdi cylinder head can be fitted to a 200tdi cylinder block, therefore can a 200tdi cylinder head (or maybe a 300tdi cylinder head) be fitted to the 2.5TD 19J engine block? The only responses are that it can't be done... However, I was reading an article that stated the 200tdi and the 19J share the same cylinder block... "(The 200tdi) ...was also loosely based on the existing 2.5-litre turbo unit, and was built on the same production line, but had a modern alloy cylinder head, improved turbocharging, intercooling and direct injection. It retained the block, crankshaft, main bearings, cambelt system and other ancillaries as the Diesel Turbo. The breather system included an oil separator filter to remove oil from the air in the system, thus finally solving the Diesel Turbo's main weakness of re-breathing its own sump oil. The 200Tdi as the new engine was called produced 111 hp (83 kW) and 195 lb·ft (264 N·m) of torque, which was nearly a 25% improvement on the engine it replaced..." I have the later type 19J engine with the revised block, improved big end bearings and re-designed breather system. Can it be done or not? If not, why not?
Following the brilliant advice here - thanks to all involved - I need to remove the residue left by the old head gasket. It was one of the new MLS type & it has left a grey residue, presumable the stuff that bonds the shim to the head. It's hard to remove & I obviously don't want to scratch the alloy.
