Good man
Timing gear is not a big issue .It just depends what needs replacing .Replace the chains /tensioners, shoes etc if I were you .
I would advise you drop the whole subframe out if you have the workspace to do so .I've taken the engine out both ways now , out the top is doable but a real pain getting it back in .
I've got shed loads of pics from my rebuilds that may help also .
Give me a call and I'll talk you through it ..............07983 144595 or 01773 761216 .
