How challenging is it to replace the front engine mount?I agree on cam and lifters if they've never been done, along with front main seal. Replace the rear main seal when replacing the flywheel and clutch. And a new thermostat wouldn't hurt. Also, consider a new engine bracket (threads tend to strip out after several timing belt changes), and perhaps a cam sprocket if you don't know who replaced the other timing belts. If they over-torqued the bolt it can deform the sprocket causing it to slip and the engine to lose time.
Also replace the front engine mount, and the dogbone if it's not been done lately.
I thought there were three 2 x Engine Mounts & Dogbone, I can do dogbone anytime and then do engine mounts when doing timing belt and water pump?Easy. You'll have it out when replacing the timing belt system.
