If timing chain jumps 10 teeth, that means costly problems. This fits with the compression tst results... and neither will start. This condition is diagnosable by a mechanic, only 'special tool' is troubleshootin skills, so maybe next time find another regular...
Minimum is new chain & guide/tightenin bit swap, seals. The chain will stretch when it jumps, dont use old one. Hopefully its only the chain, and not bent valves - I am pessimistic. I suppose that the job price is common at stealership, u should get it half price at another shop. My guess for best case scenario is 4-600$... you'll know as u first ask what timing chain swap costs. You may ask from dealers outside u area for this... The parts u quote may not be enough - what exactly are the part(s)?
Now u have dignosis, you can call shops for quotation, you already have stealership reference. IF Good shop, u get written price, & date when it supposedly ready. ...Try to ask input from friend or anybody for good shops around u, references. The price will vary depending on what is found as engine is opened. Take pessimistic view how much the total will be...
Whatever u do, let the shop u select open the engine first. STOP and no hurry. Negotiate what should be done, what has to, will be replaced, total cost... Write down these details, then ask your regular mech for opinion. Important: youre the bo$$! There is no need for you to know all bits and parts. Take second opinion, maybe have the dissassembled bitts with you in plastic bag... Your reg mech will surely give opinion free, only some leg work for u. But these are taxfee thousands, I do take lots steps for 1000$...
Meanwhile seek in the net for replacement engine (or whole wreck) so u know how much they will cost, might become cheaper? (Japanese law requires them to change engine every 3yrs, and thats why there is big supply of little used engines...)
